TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors TRANSGUARD DESCRIPTION TransGuard products are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current

Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO grains surrounded by electrically insulating barriers, creating varistor-like behavior.

The glass encapsulation provides enhanced resistance against harsh environment or process such as acids, salts, chlorite flux.

High voltage applications such as AC line protection require many grains between electrodes while low voltage requires few grains to establish the appropriate breakdown voltage.

single layer ceramic disc formulations with huge grains has had limited success.

Technology leadership in processing thin dielectric materials and patented processes for precise ceramic grain growth have yielded superior energy dissipation in the smallest size.

4 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors TRANSGUARD DESCRIPTION TransGuard products are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current characteristics (bi-directional) similar to back-to-back zener diodes. They have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO grains surrounded by electrically insulating barriers, creating varistor-like behavior. AVX VG series parts (large case size, high energy) are glass encapsulated. These parts provide the same high reliability as traditional VC series parts. The glass encapsulation provides enhanced resistance against harsh environment or process such as acids, salts, chlorite flux. The number of grain-boundary interfaces between conducting electrodes determines Breakdown Voltage of the device. High voltage applications such as AC line protection require many grains between electrodes while low voltage requires few grains to establish the appropriate breakdown voltage. Single layer ceramic disc processing proved to be a viable production method for thick cross section devices with many grains, but attempts to address low voltage suppression needs by processing single layer ceramic disc formulations with huge grains has had limited success. AVX, the world leader in the manufacture of multilayer ceramic capacitors, now offers the low voltage transient protection marketplace a true multilayer, monolithic surface mount varistor. Technology leadership in processing thin dielectric materials and patented processes for precise ceramic grain growth have yielded superior energy dissipation in the smallest size. Now a varistor has voltage characteristics determined by design and not just cell sorting whatever falls out of the process. Multilayer ceramic varistors are manufactured by mixing ceramic powder in an organic binder (slurry) and casting it into thin layers of precision thickness. Metal electrodes are deposited onto the green ceramic layers which are then stacked to form a laminated structure. The metal electrodes are arranged so that their terminations alternate from one end of the varistor to the other. The device becomes a monolithic block during the sintering (firing) cycle providing uniform energy dissipation in a small volume

11 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors TYPICAL PERFORMANCE CURVES (42 CHIP SIZE) VOLTAGE/CURRENT CHARACTERISTICS Multilayer construction and improved grain structure result in excellent transient clamping characteristics up to 2 amps peak current, while maintaining very low leakage currents under DC operating conditions. The VI curves below show the voltage/current characteristics for the 5.6V, 9V, 14V, 18V and low capacitance StaticGuard parts with currents ranging from parts of a micro amp to tens of amps. PULSE DEGRADATION Traditionally varistors have suffered degradation of electrical performance with repeated high current pulses resulting in decreased breakdown voltage and increased leakage current. It has been suggested that irregular intergranular boundaries and bulk material result in restricted current paths and other non-schottky barrier paralleled conduction paths in the ceramic. Repeated pulsing of TransGuard transient voltage suppressors with 15Amp peak 8 x 2μS waveforms shows negligible degradation in breakdown voltage and minimal increases in leakage current.

16 TransGuard Automotive Series Multilayer Varistors for Automotive Applications GENERAL DESCRIPTION The TransGuard Automotive Series are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear, bi-directional voltage-current characteristics. They have the advantage of offering bi-directional overvoltage protection as well as EMI/RFI attenuation in a single SMT package. The Automotive Series high current and high energy handling capability make them well suited for protection against automotive related transients. AVX VG series parts (large case size, high energy) are glass encapsulated. These parts provide the same high reliability as traditional VC series parts. The glass encapsulation provides also enhanced resistance against harsh environment or process such as acids, salts, chlorite flux. Operating Temperature: -55ºC to +125ºC LEAD-FREE COMPATIBLE COMPONENT FEATURES High Reliability High Energy Absorption (Load Dump) High Current Handling AEC Q2 Qualified Bi-Directional protection EMI/RFI attenuation Multi-strike capability Sub 1nS response to ESD strike APPLICATIONS Internal Combustion Engine (ICE) Vehicles Hybrid Electric Vehicles (HEV) Plug-in Hybrid Electric Vehicles (PHEV) Commercial Vehicles CAN, LIN, FLEXRAY based modules Sensors Module load dump protection Motor/inductive load transient suppression HOW TO ORDER VC AS D 4 R P Varistor Chip VC = Varistor Chip VG = Varistor Glass Encapsulated Chip Automotive Series Case Size = 3.3Vdc 5 = 5.6Vdc 9 = 9Vdc 12 = 12Vdc 14 = 14Vdc 16 = 16Vdc 18 = 18Vdc 22 = 22Vdc 26 = 26Vdc 3 = 3Vdc Working Voltage 31 = 31Vdc 34 = 34Vdc 38 = 38Vdc 42 = 42Vdc 45 = 45Vdc 48 = 48Vdc 56 = 56Vdc 6 = 6Vdc 65 = 65Vdc 85 = 85Vdc A =.1J B =.2J C =.3J D =.4J E =.5J F =.7J H = 1.2J J = 1.5J K =.6J Energy Rating L =.8J S = J X =.5J M = 1J N = 1.1J U = 4.-5.J P = J Y = J 14 = 14V 15 = 18V 22 = 22V 25 = 27V 3 = 32V 38 = 38V 39 = 42V 4 = 42V 44 = 44V 49 = 49V 54 = 54V Clamping Voltage 57 = 57V 58 = 6V 62 = 67V 65 = 67V 77 = 77V 8 = 8V 9 = 9V 11 = 1V 111 = 11V 131 = 135V 151 = 15V Package D = 7" (1)* R = 7" (4)* T = 13" (1,)* W = 7" (1,)** 42 only *Not available for 42 **Only available for 42 Termination P = Ni/Sn plated

28 StaticGuard AVX Multilayer Ceramic Transient Voltage Suppressors TYPICAL PERFORMANCE CURVES (42 CHIP SIZE) VOLTAGE/CURRENT CHARACTERISTICS Multilayer construction and improved grain structure result in excellent transient clamping characteristics up to 2 amps peak current, while maintaining very low leakage currents under DC operating conditions. The VI curves below show the voltage/current characteristics for the 5.6V, 9V, 14V, 18V and low capacitance StaticGuard parts with currents ranging from parts of a micro amp to tens of amps. PULSE DEGRADATION Traditionally varistors have suffered degradation of electrical performance with repeated high current pulses resulting in decreased breakdown voltage and increased leakage current. It has been suggested that irregular intergranular boundaries and bulk material result in restricted current paths and other non-schottky barrier paralleled conduction paths in the ceramic. Repeated pulsing of TransGuard transient voltage suppressors with 15Amp peak 8 x 2μS waveforms shows negligible degradation in breakdown voltage and minimal increases in leakage current.

MultiGuard (2& 4 Elements) AVX Multilayer Ceramic Transient Voltage Suppression Arrays ESD Protection for CMOS and Bi Polar Systems GENERAL DESCRIPTION AVX s Transient Voltage Suppression (TVS)

34 MultiGuard (2& 4 Elements) AVX Multilayer Ceramic Transient Voltage Suppression Arrays ESD Protection for CMOS and Bi Polar Systems GENERAL DESCRIPTION AVX s Transient Voltage Suppression (TVS) Arrays address six trends in today s electronic circuits: (1) mandatory ESD protection, (2) mandatory EMI control, (3) signal integrity improvement, (4) PCB downsizing, (5) reduced component placement costs, and (6) protection from induced slow speed transient voltages and currents. AVX s MultiGuard products offer numerous advantages, which include a faster turn-on-time (<1nS), repetitive strike capability, and space savings. In some cases, MultiGuard consumes less than 75% of the PCB real estate required for the equivalent number of discrete chips.

Communication BUS Varistor GENERAL DESCRIPTION The CAN BUS and FlexRay varistor is a zinc oxide (ZnO) based ceramic semiconductor device with non- linear voltage-current characteristics

42 Communication BUS Varistor GENERAL DESCRIPTION The CAN BUS and FlexRay varistor is a zinc oxide (ZnO) based ceramic semiconductor device with non- linear voltage-current characteristics (bi-directional) similar to back-to-back Zener diodes and an EMC capacitor in parallel (see equivalent circuit model). They have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO grains surrounded by electrically insulating barriers, creating varistor like behavior. AVX Communication Bus Varistors offer the advantages of large in-rush current capability, low capacitance to minimize signal distortion, fast turn on time to conservatively clamp the energy before its maximum and off state EMI filtering through their bulk capacitance. These features coupled with an extremely low FIT rate and excellent process capability make an ideal device for today's automotive or general circuit protection.

AntennaGuard 42/63 AVX Low Capacitance Multilayer Varistors ESD Protection for Antennas and Low Capacitor Loading Applications GENERAL DESCRIPTION AVX s 42/63 AntennaGuard products are an ultra-low

50 AntennaGuard 42/63 AVX Low Capacitance Multilayer Varistors ESD Protection for Antennas and Low Capacitor Loading Applications GENERAL DESCRIPTION AVX s 42/63 AntennaGuard products are an ultra-low capacitance extension of the proven TransGuard TVS (transient voltage suppression) line of multilayer varistors. RF designers now have a single chip option over conventional protection methods (passive filters with diode clamps), which not only gives superior performance over traditional schemes, but also provides the added benefits of reduced PCB real estate and lower installation costs. AVX s AntennaGuard products are available in capacitance ratings of 3pF (42 & 63 chips), 2 and 12pF (63 chip). These low capacitance values have low insertion loss, as well as give other TransGuard advantages such as small size, sub-nanosecond response time, low leakage currents and unsurpassed reliability (FIT Rate of.2) compared to diodes. RF antenna/rf amplifier protection against ESD events is a growing concern of RF circuit designers today, given the combination of increased signal gain demands, coupled with the required downsizing of the transistor package. The ability to achieve both objectives is tied to a reduced thickness of the SiO 2 gate insulator layer within the semiconductor. The corresponding result of such a change increases the Power Amplifier s (PA s) vulnerability to ESD strikes a common event with handheld electronic products with RF transmitting and/or receiving features. AVX Low Capacitance AG Series parts are ideal solution for this type of applications as well as for many more where low capacitance ESD protection is needed.

52 AntennaGuard 42/63 AVX Low Capacitance Multilayer Varistors ESD Protection for Antennas and Low Capacitor Loading Applications Antenna Varistors AVX offers a series of 42 and 63 chip varistors, designated the AntennaGuard series, for RF antenna/rf amplifier protection. These devices offer ultra-low capacitance (<3pF in 42 chips, and 3pF & 12pF in 63 packages), as well as low insertion loss. Antenna varistors can replace output capacitors and provide ESD suppression in RF and capacitance sensitive applications. It is very common to employ some form of a FET in many types of efficient/miniature RF amplifiers. Typically, these RF transistors have nearly ideal input gate impedance and outstanding noise figures. However, FETs are very susceptible to ESD damage due to the very thin layer of SiO 2 uses as the gate insulator. The ultra-thin SiO 2 layer is required to improve the gain of the transistor. In other words, the upside of the performance enhancement becomes the downside of the transistors survival when subjected to an ESD event. ESD damage to the RF Field Effect Transistors (FETs) is a Suppression Device growing concern among RF designers due to the following trends: (1) RF amplifiers continue to shrink in size, and (2) FET gains figures continue to increase. Both trends relate to decreasing gate oxide thickness, which in turn, is directly proportional to increased ESD sensitivity. As miniaturization trends accelerate, the traditional methods to protect against ESD damage (i.e., PC board layout, passive filters, and diode clamps) are becoming less and less effective. AVX s AntennaGuard varistor can be used to protect the FET and offer superior performance to the previously mentioned protection methods given above.

88 TransFeed AVX Multilayer Ceramic Transient Voltage Suppressors TVS Protection and EMI Attenuation in a Single Chip GENERAL DESCRIPTION AVX has combined the best electrical characteristics of its TransGuard Transient Voltage Suppressors (TVS) and its Feedthru Capacitors into a single chip for state-of-the-art overvoltage circuit protection and EMI reduction over a broad range of frequencies. This unique combination of multilayer ceramic construction in a feedthru configuration gives the circuit designer a single 85 chip that responds to transient events faster than any TVS device on the market today, and provides significant EMI attenuation when in the off-state. The reduction in parallel inductance, typical of the feedthru chip construction when compared to the construction of standard TVS or ceramic capacitor chips, gives the TransFeed product two very important electrical advantages: (1) faster turn-on time. Calculated response times of <2 psec are not unusual with this device, and measured response times range from 2 25 psec. The TransFeed turn-on characteristic is less than half that of an equivalent TransGuard part and TransGuards clamp transient voltages faster than any other bipolar TVS solution such as diodes; (2) the second electrical advantage of lower parallel inductance, coupled with optimal series inductance, is the enhanced attenuation characteristics of Schematic Diagram IN OUT Electrical Model IN L S L S R V C R P R ON L P OUT the TransFeed product. Not only is there significantly greater attenuation at a higher self-resonance frequency, but the roll-off characteristic becomes much flatter, resulting in EMI filtering over a much broader frequency spectrum. Typical applications include filtering/protection on Microcontroller I/O Lines, Interface I/O Lines, Power Line Conditioning and Power Regulation. GENERAL CHARACTERISTICS Operating Teperature: -55 C to +125 C Working Voltage: 5.6Vdc - 26 Vdc Case Size: 85 Energy Rating:.5 -.3J Current: 2-12A Max Feedthru Current:.5-1A TYPICAL APPLICATIONS Fingerprint ID Circuit Magnetic Field Circuit LCD Dashboard Driver Where designers are concerned with both transient voltage protection and EMI attenuation, either due to the electrical performance of their circuits or due to required compliance to specific EMC regulations, the TransFeed product is an ideal choice.

93 TransFeed AVX Multilayer Ceramic Transient Voltage Suppressors TVS Protection and EMI Attenuation in a Single Chip PERFORMANCE CHARACTERISTICS FEEDTHRU VARISTORS AVX Multilayer Feedthru Varistors (MLVF) are an ideal choice for system designers with transient strike and broadband EMI/RFI concerns. Feedthru Varistors utilize a ZnO varistor material and the electrode pattern of a feedthru capacitor. This combination allows the package advantage of the feedthru and material advantages of the ZnO dielectric to be optimized. ZnO MLV Feedthrus exhibit electrical and physical advantages over standard ZnO MLVs. Among them are: 1. Faster Turn on Time 2. Broadband EMI attenuation 3. Small size (relative to discrete MLV and EMI filter schemes) The electrical model for a ZnO MLV and a ZnO Feedthru MLV are shown below. The key difference in the model for the Feedthru is a transformation in parallel to series inductance. The added series inductance helps lower the injected transient peak current (by 2πfL) resulting in an additional benefit of a lower clamping voltage. The lowered parallel inductance decreases the turn on time for the varistor to <25ps.

121 TransGuard Automotive Series AVX Multilayer Transient Voltage Protection Circuit Protection in Automotive Applications AUTOMOTIVE TRANSIENTS Todays automobiles are using new technologies based on electronics systems connected by wide variety of networks to provide increased safety, convenience and comfort, to reduce emissions, increase fuel efficiency and more. During the lifetime these systems are subjected to many overvoltage transient surges. To ensure safe and reliable function it is necessary to protect these sensitive systems againts overvoltage surges. Automotive Power Rail Transients The transients on automotive power rails are usually medium to high energy transients and are caused by engine start such as Jump start (connecting other cars battery to jump start the engine), Load Dump (sudden load disconnect from alternator) or inductive switching (caused by DC motors on/off switching - e.g. window lifter, wipers, adaptive headlights). These transients are typically bi-directional. AVX MULTILAYER VARISTORS The EMC requirements of today s automotive electronics are a natural fit for the use of AVX MultiLayer Varistors (MLVs). AVX AUTOMOTIVE VARISTORS ADVANTAGES AEC-Q2 qualified Bi-directional protection Compact footprint Very fast response - sub ns EMI/RFI filtering in the off state Multiple strikes capability No derating over operating temperature range (-55 C to +125 C, 15 C available) RoHS compliant Optional hybrid termination (Pd/Ag) available Nominal Voltage V ±25kV Air Discharge ±8kV HBM 8V Machine Model 2kV Charge Device Model AVX Automotive Series Varistors provide reliable protection against automotive related transients - such as Load Dump, Jump Start and ESD to protect the growing number of electronics systems used in automotive applications. Transient examples: Load dump (ISO ) AEC-Q2-2 CI-22 Jump Start ISO 165 CI-26 ISO 7637 Pulse 1-3 ISO IEC , etc. Automotive Data Line Transients Data lines connecting the automotive systems need to be protected against varisous ESD pulses to ensure sensitive electronics protection. These transients are mainly caused by human interaction with the electronics systems (controls, buttons, ports) or by interaction between systems due to different charge build up. These transients are typically bidirectional and very fast. The parts offer fast turn on time, bi-directional protection, excellent multiple strikes capability and in addition also EMI/RFI filtering in the off-state that can improve overall system EMC performance. High power MLV designs have been revised and miniaturized to allow efficient protection of today s most widely used communication bus designs. When used in communication bus designs, MLVs can save approximately 9% of the board area involved with diode/emc cap solutions. In addition, MLVs offer a FIT rate <.1, an ability to be used at temperatures up to 15 C and a fast turn on time.

122 TransGuard Automotive Series AVX Multilayer Transient Voltage Protection Circuit Protection in Automotive Applications MLVs have traditionally been used in inductively generated automotive transient suppression applications such as motors, relays and latches. MLVs offer a large in rush current capability in a small package, high-energy transient suppression and a broad and definable off state bulk EMC capacitance.

132 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: IEC 61-4 Requirements WHAT IS IEC 61-4? The International Electrotechnical Commission (IEC) has written a series of specifications, IEC 61-4, which mandate the performance of all electronic devices in a variety of transient and incident RF conditions. This specification requirement resulted as part of Europe s move toward a single market structure and a desire to formalize and harmonize current member countries requirements. As of January 1, 1996, all electronic and electrical items sold to Europe must meet IEC 61-4 series specifications. WHY IS IEC 61-4 REQUIRED BY EUROPE? The various regulatory agencies within Europe feel that the IEC 61-4 series of specifications is necessary to insure acceptable performance of electronic equipment in a world filled with increasingly more Electromagnetic Interference - EMI. Furthermore, as electronic systems become more portable, and the transient susceptibility of semiconductors increases, government regulations are essential to maintain a minimum level of performance in all equipment. Europe is so serious about the problem that they require that equipment be certified via testing to meet IEC 61-4 series specifications after 1/1/96 to avoid fines and prosecution. HOW DO COMPANIES SELLING ELECTRONIC SYSTEMS MEET IEC 61-4 PARTS 2-5 SPECIFICATIONS? Companies and design engineers must now use protective circuits or devices to meet these requirements. First, a description of IEC 61-4/2-6 is in order: IEC ESD TESTING REQUIREMENTS All equipment destined for Europe must be able to withstand 1 strikes of ESD waveforms with Tr < 1ns in contact discharge mode (preferred) at pre-selected points accessible during normal usage or maintenance. Testing shall be performed at one or more of four (4) severity levels, depending upon equipment category. Level Contact Discharge 1 Air Discharge Mode Mode Test Voltage Test Voltage kv kv Test Conditions 1 Preferred mode of testing due to repeatability. WAVEFORM PARAMETERS Level Test First Peak TR 3 ns 6 ns Voltage of ns Current Current Level Discharge Amps ± Amps ± kv Current 3% 3% Amps ± 1% Upon completion of the test, the system must not experience upset (data or processing errors) or permanent damage. The waveforms are to be injected at or along the DUT s body which is accessible in normal set-up and operation. IEC ELECTROMAGNETIC COMPATIBILITY IMPACT TESTING (EMC) This test is concerned with the susceptibility of equipment when subjected to radio frequencies of 27 MHz to 5 MHz. The system must be able to withstand three (3) incident radiation levels: Level 1 1V/m field strength Level 2 3V/m field strength Level 3 1V/m field strength Level X User defined > 1V/m field strength The system must not experience upset (data or processing errors) or permanent errors. IEC ELECTRICAL FAST TRANSIENT (EFT) TESTING The EFT test is modeled to simulate interference from inductive loads, relay contacts and switching sources. It consists of coupling EFT signals on I/O parts, keyboard cables, communication lines and power source lines. The system, depending upon appropriate severity level, must be able to withstand repetition rates of 2.5 khz to 5 khz for 1 minute as follows: Open Circuit Output Voltage/1% On Power Supply On I/O, Signal, Data, Control lines Level 1.5kV.25kV Level 2 1kV.5kV Level 3 2kV 1kV Level 4 4kV 2kV 13

133 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: IEC 61-4 Requirements IEC UNIDIRECTIONAL POWER LINE SURGE TEST The details of this specification for high energy disturbances are being addressed in several drafts under discussion within the EC at this time. IEC CONDUCTED RF TEST FROM 9kHz TO 8MHz The details of this specification for conducted broad band RF signals are being addressed in a first edition draft within the EC at this time. Designers have the option of using AVX TransGuards to meet IEC , 3 and 4. In the case of IEC TransGuards can be used to suppress the incoming Transient just like a Zener diode would. TransGuards, however, exhibit bipolar characteristics, a faster turn-on-time (<1nS), a better repetitive strike capability and superior thermal stability to the Zener suppression device. Furthermore, TransGuards are typically smaller and lighter when placed on SMT circuit boards. See Figure 1 for data illustrating IEC repetitive strike capability. The TransGuards effective capacitance allows the device to be used to meet IEC and The device s parallel capacitance can be used as effectively as a capacitor to block low level incident and conducted RF energy. If in the case of some levels of IEC and IEC when the intensity of pulse is greater than the device s breakdown capability it will then turn on and suppress via MOV means rather than capacitance (as in the small signal case). Effectiveness hinges upon the proper placement of the device within the PCB (which is usually easily accomplished since TransGuards are so small). SUMMARY AVX TransGuards are exceptionally suited to meet the defined portions of the IEC 61-4 document. Experimentation is critical to proper choice and selection of devices to suppress /4.

TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Turn on Time Characteristics of AVX Multilayer Varistors INTRODUCTION Due to the growing importance of ESD immunity

134 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Turn on Time Characteristics of AVX Multilayer Varistors INTRODUCTION Due to the growing importance of ESD immunity testing, as required by the EMC Directive, proper selection of voltage suppressor devices is critical. The proper selection is a function of the performance of the device under transient conditions. An ideal transient voltage suppressor would reach its clamping voltage in zero time. Under the conditions imposed by the 1991 version of IEC , the actual turn-on-time must be less than one nanosecond to properly respond to the fast leading edge of the waveform defined in the standard. It has been found during testing of transient suppressors that the response time is very closely dictated by the packaging of the device. Inductance that is present in the connection between the silicon die and the leads of the device creates an impedance in series with the suppressor device; this impedance increases the overall device response time, reducing the effectiveness of the suppressor device. The purpose of this paper is to present the Turn on Time characteristics of Multilayer Varistors (MLVs) and to compare the MLV Turn on Time to that of various silicon transient voltage suppressors (SiTVs). The Turn on Time of a transient voltage suppressor (TVS) is of growing importance since IEC now specifies ESD waveform with a rise time < 1 ns. Therefore, TVS s must have a turn on time < 1 ns to effectively suppress ESD. In many, if not all, ESD suppression applications, TVS turn on time can be of more importance than absolute clamping voltage (Vc) of the TVS (assuming that the TVS clamping voltage is less than the damage voltage of the circuit or IC). To measure the turn on time of today s TVS s, a broad cross section of MLVs and SiTVs were chosen. Only surface mount devices were chosen in order to best represent today s TVS current usage/trends and to keep the test matrix to a reasonable level of simplicity. The following devices were tested: SMT MLV SiTVS MA141WA 63 BAV SOT 23 type 126 SMB - 5W gull-wing SM device 121 SMC - 15W gull-wing SM device TEST PROCEDURE The TVS device under test (DUT) was placed on a PCB test fixture using SN6/4 solder. The test fixture (see Figure 1) was designed to provide an input region for an 8kV contact ESD discharge waveform (per IEC level 4 requirements). In addition, the fixture was designed to provide low impedance connections to the DUTs. Figure 1. DUT Test Fixture The ESD pulse was injected to the PCB from a Keytek minizap ESD simulator. Additionally, the fixture was to channel the ESD event to a storage oscilloscope to monitor the suppressor s response. Six resistors were used on the PCB to provide waveshaping and an attenuated voltage to the storage scope (see Figure 2): MINI-ZAP with CONTACT DISCHARGE TIP "LAUNCH AREA" R1 1.6k R2 1.6k R3 1.6k DEVICE UNDER TEST R4 1k R5 1k R6 2 Figure 2.

135 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Turn on Time Characteristics of AVX Multilayer Varistors The functions of the resistors are as follows: The resistor values were adjusted in open circuit conditions to obtain best open circuit response. R1, R2 (1.6K) - provide wave shaping during the ESD discharge event R3 (1.6K), R4 (1K), R5 (1K) - Form a 6 db Attenuator (1:1 ratio) for input of Tektronix TDS 54 1 giga sample/second storage oscilloscope R6 (2 Ω) - provides matching to the 5 ohm coax feeding the TDS 54 oscilloscope. The open circuit response of the ESD test fixture with a 9kV ESD pulse is shown in Figure 3. Task Stopped: 1. CH1 Figure 3. Open Circuit Response of Test Fixture to an Injected ESD Waveform The graph shows the voltage attenuated by a factor of 1, with a 8ps risetime for the ESD waveform (this agrees with typical data given by Keytek for equipment performance). It should be noted that only the positive polarity was tested. Prior testing showed turn on time was not dependent upon waveform polarity (assuming that DUTs are bidirectional). TEST RESULTS 74 Acquisitions 2. V M 2.ns CH1 2.2 V Δ: 8ps O: -1.2ns CH1 Rise 8ps MLV TURN ON TIME TRANSGUARDS The turn on time test results for AVX TransGuards showed that all case sizes were capable of a sub-nanosecond turn on response. This corresponds favorably with the calculated turn on time of less than 1 ns. Specific performance data follows: AVX TransGuard CASE SIZE TURN ON SPEED 63 <.7 ns 85 <.9 ns 126 <.9 ns 121 <.8 ns TVS TURN ON TIME Test results for SiTVs varied widely depending upon the physical size and silicon die mounting configuration of the device. The results agree with several SiTVs manufacturers papers indicating that the absolute response from the silicon die could be < 1 ns. However, when the die is placed in a package, the turn on time delay increases dramatically. The reason for this is the series inductance of the SiTVs packaging decreases the effective response time of the device. Reports of 1-5 ns are frequently referred to in SiTVs manufacturers publications. Further, the turn on times for SiTVs vary dramatically from manufacturer to manufacturer and also vary within a particular manufacturers lot. The data provided in the following table generally agreed with these findings: SUMMARY This test confirms calculations that show that AVX TransGuards have a true sub-nanosecond turn on time. Although the silicon die of a SiTVs has a sub-nanosecond response, the packaged SiTVs typically has a response time much slower than a TransGuard. If the two devices were directly compared on a single graph (see Figure 4), it could be shown that the TransGuard diverts significantly more power than even the fastest SiTVs devices. Additionally, TransGuards have a multiple strike capability, high peak inrush current, high thermal stability and an EMI/RFI suppression capability which diodes do not have.

136 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: The Impact of ESD on Insulated Portable Equipment The purpose of this discussion is to recap the impact ESD has on portable, battery powered equipment. It will be shown that ESD can cause failures in floating ground systems in a variety of ways. Specifically, ESD induced failures can be caused by one or more of its complex components: Predischarge - Corona Generated RF Predischarge - E Field Discharge - Collapsing E Field Discharge - Collapsing H Field Discharge - Current Injection...Voltage...Additional Fields With this in mind it will be shown that the only way to insure equipment survivability to ESD is to use a Transient Voltage Suppressor (in addition to proper circuit layout, decoupling, and shielding). In order to get a better understanding of what happens in an ESD event the charge developed by a human body should be defined. The ESD schematic equivalent of the human body model is shown in Figure 1. Typically, the charge developed on a person can be represented by a 15pF capacitor in series with a resistance of 33 ohms. The energy of an ESD waveform generated from this model is Q = 1/2 CV 2 where Q = total energy in Joules, C = capacitance of the human body model in farads and V = charging voltage in volts. Voltages can be as high as 25 kv, however typical voltages seen are in the 8 to 15 kv regions. In the predischarge scenario (Figure 2) a human charged to 2 kv may approach a battery powered system on a table. As the person reaches toward the system electrostatics dictate that the system will have an equal and opposite charge on the system s surface nearest to the person. SInce the system we are approaching is isolated from ground, the charge is only redistributed among the device. (If the system were grounded a current would be generated by the loss of electrons to ground. The system would then become positive relative to ground). The rate of approach of the human body model affects the charging current to a small extent. However, most importantly, it is the electrostatic field and the unequal voltages which developed across the equipment that cause the destruction of components within the system. In general, unprotected IC s (particularly CMOS) are susceptible to damage due to induced E field voltages. This problem is further complicated by the device type and complexity and the fact that the breakdown voltage of a generic IC will vary greatly from manufacturer to manufacturer (Figure 3). This brief discussion should be adequately convincing that electrostatically induced E field can impact system reliability. IC protection can be achieved by placing a transient suppressor on the most susceptible pins of the sensitive IC s (e.g., Vcc and I/O pins, etc.). 1 IC TYPE vs SUSCEPTIBILITY R H Where: C H = Human body model capacitance typically 15pF VOLTS 1 1 C H Figure 1.

POSITIVE INDUCED VOLTAGE 2 kv RESULTING NEGATIVE CHARGE NEGATIVE 2 kv CHARGE Figure 3. IC Type E Field Susceptibility CONTACT DISCHARGE FAILURES As the charged person gets closer to the system, the situation is more complex. First a much more detailed human body model is needed to represent the complex transmission line which will transport energy to the system (see Figure 4). In this discussion we will only consider the case of a single contact discharge. In the real world, however, multiple discharges will likely occur (possibly caused by a person s hand reacting to an ESD spark and then touching the system again, etc.). In contact discharge, when a charged person approaches the system, E fields are induced. As the person gets closer to the system, the field intensity becomes greater, eventually reaching a point large enough to draw an arc between the Figure 2. Pre-Discharge Scenario 134

137 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: The Impact of ESD on Insulated Portable Equipment person and the system. In contrast to the noncontrast E field example, the speed of approach is of great importance in the contact discharge model. A fast approach causes a more intensive discharge and faster current rise times and peaks. The model shown on Figure 4 can be broken up into 4 sections for the sake of simplification. The first section is the human body model input voltage. This section is identical to the simplified human body model shown in Figure 1. Section 2 takes into account how the human body model gets the energy to the system. This section considers the inductance, resistance and capacitance of the human s arm and finger and its capacitance relative to ground and the system. The third section is the inductance and resistance of the arc which is created as section 2 approaches the system (Section 4). Section four is the system itself. The combination of the capacitances and inductances in these sections form a complex network of LC tank circuits which will inject a variety of waveforms (transients) into the system. These waveforms will range in frequency from very high (5 GHz) to high (1 MHz) to low (2-5 MHz) plus a variety of under damped and over damped waveforms. Finally, in addition to current/voltage injection occurring as a result of the discharge, there will be collapsing E and H fields and significant high frequency RF waveforms. Many times these waveforms propagate into shielded equipment and cause system/device failures. SUMMARY Designers may be inclined to think that E field variation due to near field electrostatics (as in the person being close to the system but not touching it) can be eliminated by shielding. This is usually not the case because it is difficult to get a tight columbic shield around internal circuitry without incurring significant additional manufacturing costs. Additionally, the shielding will likely have seams, ventilation holes, or I/O ports which represent a significant portion of a wavelength (at 5 GHz). Therefore, E fields and corona generated RF can be a problem. Finally, if the system has I/O connectors, keyboards, antennas, etc., care must be taken to adequately protect them from direct/and indirect transients. The most effective resolution is to place a TransGuard as close to the device in need of protection as possible.these recommendations and comments are based upon case studies, customer input and Warren Boxleitner s book Electrostatic Discharge and Electronic Equipment - A Practical Guide for Designing to Prevent ESD Problems.

138 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Motor and Relay Application Study PURPOSE A significant number of end customers have experienced failures of circuitry in and around low voltage relays and motors. Additionally, EMI problems have been associated with running motors. This study is aimed at evaluating how TransGuards can reduce EMI from running motors and clamp transients generated from relays and motors during power off. DESCRIPTION Three different motors and two different relays were chosen to represent the wide range of possible devices used by designers. Device choices were as follows: MOTORS Cramer Comair Comair RELAYS Potter and Brumfield 81 series Geared Motor 12V, 3rpm (48 RPM armature speed) 17ma Start/Run Torque 3oz Rotron DC Biscut Fan - 24V, 48ma Rotron DC Biscut Fan - 12V, 9ma Potter and Brumfield 24V Relay 1 3 HP 12V AC, 1A 24 VAC Rating 12V Relay 1 3 HP 12V AC, 1A 24 VAC Rating A Tektronix TDS 784A four channel 1GHz 4G S/s digitizing storage scope was used to capture the -1 2 LI2 transient peak from the relays and motors. A x1 probe was connected to the scope and one leg of the relay/motor coil; the probe s ground was connected to the other relay coil/motor wire. The scope was triggered on the pulse and waveforms printed. When suppression was introduced into the circuit, it was placed directly on the relay coils/motor lead wires. The axial TransGuard and capacitors had a 19mm (3 4") total lead length in each case. Upon careful consideration, it was determined that this was a fairly common lead length for such applications. SUMMARY GEARED MOTOR The Cramer geared motor was tested while running (under load) to determine its on state noise as well as under loaded turn off conditions. Both TransGuards and ceramic capacitors were tested to determine the level of protection they offer. A 14V axial TransGuard provided the best protection during running and turn off. The VA114D3 TransGuard cut the 6V unprotected turn off voltage spike to 3V. It also cut the on state noise to 4.V pk-pk due to its internal capacitance.

141 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Multilayer Varistors In Automobile MUX Bus Applications The current trend in automobiles is towards increased performance, comfort and efficiency. To achieve these goals, automobile companies are incorporating an ever increasing array of electronics into cars. As the electronic content within cars increases, auto manufacturers are utilizing multiplex bus designs to network all the sensors to a central point (usually the engine control unit [ECU]). Multiplex lines save wiring harness weight and decrease the harness complexity, while allowing higher communication speeds. However, the multiplex structure tends to increase the occurrence and severity of Electromagnetic Interference (EMC) and Electrostatic Discharge (ESD). Multilayer varistors (MLVs) are a single component solution for auto manufacturers to utilize on multiplex nodes to eliminate both ESD and EMC problems. MLVs also offer improved reliability rates (FIT rates <1 failure/billion hours) and smaller designs over traditional diode protection schemes. TYPICAL MUX NODE APPLICATION There are a variety of SAE recommended practices for vehicle multiplexing (J-185, J-1939, J-178, J-1587, CAN). Given the number of multiplexing specifications, it is easy to understand that bus complexity will vary considerably. Each node has an interface circuit which typically consists of a terminating resistor (or sometimes a series limiting resistor), back to back Zener diodes (for over voltage protection) and an EMC capacitor. Such a method is compared to that of a multilayer varistor in Figure 1. XCVR BUS XCVR BUS MLV PROTECTION METHOD SINGLE COMPONENT SOLUTION To more clearly understand the functional structure of a MLV, see the equivalent electrical model shown in Figure 2.

Comparison of past node protection methods to MLV node protection methods. BODY INDUCTANCE DEVICE CAPACITANCE VOLTAGE VARIABLE RESISTOR INSULATION RESISTANCE As the schematic in Figure 1 illustrates, the implementation of MLV protection methods greatly simplifies circuit layout, saves PCB space and improves system reliability. The MLV offers many additional electrical improvements over the Zener/passive schemes. Among those advantages are higher multiple strike capability, faster turn on time and larger transient overstrike capability. Further clarification on the types of varistors compared to the performance of Zener diodes follows. CONSTRUCTION AND PHYSICAL COMPARISON The construction of Zinc Oxide (ZnO) varistors is a well known, relatively straightforward process in which ZnO grains are doped with cobalt, bismuth, manganese and other oxides. The resulting grains have a Schottky barrier at the grain interface and a typical grain breakdown voltage (V b ) of approximately 3.6V per grain. Currently, there are two types of varistors. Single layer varistors (SLVs) an older technology referred to as pressed pill, typically are larger, radial leaded components designed to handle significant power. Multilayer varistors (MLVs) are a relatively new technology packaged in true EIA SMT case sizes. Beyond the ZnO material system and grain breakdown similarity, MLVs and SLVs have little in common. That is, to design a low voltage SLV, the grains must be grown as large as possible to achieve a physically large enough part to be handled in the manufacturing process. Typically it is very difficult to obtain a consistent grain size in a low voltage SLV process. The electrical performance of SLV is affected by inconsistent grain size in two ways. First, low voltage SLVs often exhibit an inconsistent V b and leakage current (I L ) from device to device within a particular manufacturing lot of a given rating. This contributes to early high voltage repetitive strike wear out. Secondly, SLVs with similar voltage and energy ratings as MLVs typically exhibit a lower peak current capability due in part to increased resistance of the long current path of the large grains. This contributes to early repetitive high current wear out. At higher voltages, the grain size variations within SLVs play a much smaller percentage role in V b and leakage current values. As a result, SLVs are the most efficient cost effective way to suppress transients in high voltages (e.g., 115 VAC, 22 VAC). Figure 2. TransGuard Equivalent Model. 139

142 TransGuard AVX Multilayer Ceramic Transient Voltage Suppressors Application Notes: Multilayer Varistors In Automobile MUX Bus Applications MLV MANUFACTURE The construction of a MLV was made possible by employing a variety of advanced multilayer chip capacitors (MLCC) manufacturing schemes coupled with a variety of novel and proprietary ZnO manufacturing steps. In the MLCC process, thin dielectrics are commonly employed to obtain very large capacitance values. It is that capability to design and manufacture multilayer structures with dielectric thicknesses of 1 mil that allows MLVs to be easily made with operating/ working voltages (V wm ) as low as 3.3V (for use in next generation silicon devices). Once a particular working voltage has been determined (by altering the ZnO dielectric thickness), the multilayer varistor's transient energy capability is determined by the number of layers of dielectric and electrodes. It is, therefore, generally easy to control the grain size and uniformity within a MLV due to the relative simplicity of this process. MLVs exhibit capacitance due to their multiple electrode design and the fact that ZnO is a ceramic dielectric. This capacitance can be utilized with the device s series inductance to provide a filter to help limit EMI/RFI. The equivalent model of a MLV is shown in Figure 2. MLVs are primarily used as transient voltage suppressors. In their on state, they act as a back-to-back Zener, diverting to ground any excess, unwanted energy above their clamping voltage. In their off state, they act as an EMC capacitor (capacitance can be minimized for high speed applications). A single MLV, therefore, can replace the diode, capacitor and resistor array on multiplex node applications. Any TVS will see a large number of transient strikes over its lifetime. These transient strikes will result from different events such as well known ESD HBM, IC MM, alternator field decay, load dump models and uncontrolled random events. It is because of the repetitive strikes that all TVS suppressors should be tested for multiple strike capability. Typically, a TVS will fail due to high voltage, high current or over-energy strikes. High voltage repetitive strikes are best represented by IEC kV waveforms. MLVs demonstrate a greatly superior capability to withstand repetitive ESD high voltage discharge without degradation. Repetitive Strike Performance 8X2 μs 15A High current repetitive strikes are represented by 8x2μs 15A waveforms. A comparison between MLVs, SLVs and SiTVS is shown in Figures 3A, B, C respectively. SILICON TVS MANUFACTURE The construction of a silicon TVS departs dramatically from that of either single layer varistor or multilayer varistor construction. Devices are generally produced as Zener diodes with the exception that a larger junction area is designed into the parts and additional testing was likely performed. After the silicon die is processed in accordance to standard semi-conductor manufacturing practice, the TVS die is connected to a heavy metal lead frame and molded into axial and surface mount (SMT) configuration. MLVs COMPARED TO DIODES The response time for a silicon diode die is truly subnanosecond. The lead frame into which the die is placed and the wire bonds used for die connections introduce a significant amount of inductance. The large inductance of this packaging causes a series impedance that slows the response time of SiTVS devices. A best case response time of 8nS on SOT23 and a 1.5nS to 5nS response time on SMB and SMC products respectively are rather typical. MLVs turn on time is <7nS. MLVs turn on time is faster than SiTVS and that fast turn on time diverts more energy and current away from the IC than any other protection device available. CONCLUSION 15 AMP Current Repetitive Strike Comparison The technology to manufacture MLVs exists and allows the manufacture of miniature SMT surge suppressors. MLVs do not have the wear out failure mode of first generation (single layer) varistors. In fact, MLVs exhibit better reliability numbers than that of TVS diodes. MLVs are a viable protection device for auto multiplex bus applications.

145 TransGuard AVX Multilayer Varistors Assembly Guidelines HANDLING MLVs should be handled with care to avoid damage or contami nation from perspiration and skin oils. The use of tweezers or vacuum pickups is strongly recommended for individual components. Bulk handling should ensure that abrasion and mechanical shock are minimized. Taped and reeled components provide the ideal medium for direct presentation to the placement machine. PREHEAT It is important to avoid the possibility of thermal shock during soldering and carefully controlled preheat is therefore required. The rate of preheat should not exceed 4 C/second and a target figure 2 C/second is recommended. SOLDERING Mildly activated rosin fluxes are preferred. The minimum amount of solder to give a good joint should be used. Excessive solder can lead to damage from the stresses caused by the difference in coefficients of expansion between solder, chip and substrate. AVX terminations are suitable for all wave and reflow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools. COOLING Natural cooling in air is preferred, as this minimizes stresses within the soldered joint. When forced air cooling is used, cooling rate should not exceed 4 C/second. CLEANING Flux residues may be hygroscopic or acidic and must be removed. AVX MLVs are acceptable for use with all of the solvents described in the specifications MIL-STD-22 and EIA-RS-198. Alcohol-based solvents are acceptable and properly controlled water cleaning systems are also acceptable. Many other solvents have been proven successful, and most solvents that are acceptable to other components on circuit assemblies are equally acceptable for use with MLVs. POST SOLDER HANDLING Once the components are soldered to the board, any bending or flexure of the PCB applies stresses to the soldered joints of the components. For leaded devices, the stresses are absorbed by the compliancy of the metal leads and generally don t result in problems unless the stress is large enough to fracture the soldered connection. Surface mount devices are more susceptible to such stress because they don t have compliant leads and are brittle in nature. The most frequent failure mode is high leakage current (or low breakdown voltage). Also, a significant loss of capacitance due to severing of contact between sets of internal electrodes may be observed. Cracks caused by mechanical flexure are very easily identified and generally take one of the following two general forms: Type A: Angled crack between bottom of device to top of solder joint. Type B: Fracture from top of device to bottom of device. Mechanical cracks are often hidden underneath the termination and are difficult to see externally. However, if one end termination falls off during the removal process from PCB, this is one indication that the cause of failure was excessive mechanical stress due to board flexure. COMMON CRACKS OF MECHANICAL CRACKING The most common source for mechanical stress is board depanelization equipment, such as manual breakapart, v- cutters and shear presses. Improperly aligned or dull cutters may cause torquing of the PCB resulting in flex stresses being transmitted to components near the board edge. Another common source of flexural stress is contact during parametric testing when test points are probed. If the PCB is allowed to flex during the test cycle, nearby components may be broken. A third common source is board-to-board connections at the vertical connectors where cables or other PCBs are connected to the PCB. If the board is not supported during the plug/unplug cycle, it may flex and cause damage to nearby components. Special care should also be taken when handling large (>6" on a side) PCBs since they more easily flex or warp than smaller boards. 143

146 TransGuard AVX Multilayer Varistors Assembly Guidelines REWORKING ASSEMBLIES Thermal shock is common in MLVs that are manually attached or reworked with a soldering iron. AVX strongly recommends that any reworking of MLVs be done with hot air reflow rather than soldering irons. Direct contact by the soldering iron tip often causes thermal cracks that may fail at a later date. If rework by soldering iron is absolutely necessary, it is recommended that the wattage of the iron be less than 3 watts and the tip temperature be <3 C. Rework should be performed by applying the solder iron tip to the pad and not directly contacting any part of the component. VARISTOR SOLDERABILITY Historically, the solderability of Multilayer Varistors (MLVs) has been a problem for the electronics manufacturer. He was faced with a device that either did not wet as well as other electronic components, or had its termination material leached away during the assembly process. However, by utilizing proprietary procedures, AVX Corporation provides the market with a MLV that has solderability comparable to that of other electronic components, and resists leaching during assembly. Clearly, a plated termination system (as seen in Figure 3) is desired. This system, which is typical of other electronic components such as capacitors and resistors, produces a much better assembled product. Figure 2 Leaching of Unplated Terminations Non-Wetting of Unplating Terminations BACKGROUND The basic construction of an unplated MLV is presented in Figure 1. The external termination is a metal that connects Ceramic Figure 1 Unplated MLV p Electrodes Thick Film Material the internal electrodes to the circuitry of the assembly using the MLV. The external electrode must accomplish two goals. First, it must be sufficiently solderable to allow the solder used in assembly to wet the end of the chip and make a reliable connection to the traces on the circuit board. Second, it must be robust enough to withstand the assembly process. This is particularly important if wave soldering is used. Unfortunately these two goals are competing. In order to achieve good solderability, an alloy high in silver content is chosen. However, this alloy is prone to leaching during assembly, so an additional metal is added to improve the leach resistance. While this improves the leach resistance, this addition makes the termination less solderable. The results are either terminations that leach away, or do not solder well (see the photographs in Figure 2). Ceramic Electrodes Figure 3 Plated MLV Solder Layer Nickel Layer Thick Film Material In the plated termination, the base termination layer is still used (it provides contact from the electrodes to the circuitry). On top of the base termination is a layer of nickel. This is the surface to which the solder bonds during assembly. It must be thick enough to stay intact during IR reflow or wave 144

The solder preserves the solderability of the nickel layer. It must be thick and dense to keep oxygen and water from reaching the nickel layer.

147 TransGuard AVX Multilayer Varistors Assembly Guidelines soldering so that the thick film material does not leach away. It must also be thick enough to prevent the inter-metallic layer between the thick film termination and the nickel layer from affecting the solderability. In order to protect the nickel (i.e., maintain its solderability), a layer of solder is plated on top of the nickel. The solder preserves the solderability of the nickel layer. It must be thick and dense to keep oxygen and water from reaching the nickel layer. Figure 5 AVX Plated Parts THE CHALLENGE Zinc oxide varistors are semi-conductive in nature that is what allows them to turn on and divert a damaging transient away from sensitive electronic circuitry and safely to ground. This semi-conduction poses a major problem for the manufacturer that wants to plate the terminations the ceramic plates also! This condition, overplating, must be controlled, as it is cosmetically undesirable and could result in an unwanted path of conduction across the chip. Early efforts in plating MLVs revolved around limiting the time that the chip was in the plating bath. This helped prevent overplating, but also produced chips with marginal solderability. The photographs in Figure 4 depict the problems that occur when the plated layers are not thick enough. THE SOLUTION AVX has developed a proprietary process that passivates the ceramic surface of the MLV. This allows us to plate the parts for a longer time without getting the overplate. This results in significantly thicker layers of nickel and alloy plated onto the base termination. These thicker layers translate into bond strengths that are typically twice those of our competitors and solder fillets and parts that pass all measured of solderability (as seen in Figure 5).
