Overvoltage Suppression Facts Transient Threats What Are Transients? Voltage Transients are defined as short duration surges of electrical energy and are the result of the sudden release of energy previously stored or induced by other means, such as heavy inductive loads or lightning. In electrical or electronic circuits, this energy can be released in a predictable manner via controlled switching actions, or randomly induced into a circuit from external sources. Repeatable transients are frequently caused by the operation of motors, generators, or the switching of reactive circuit components. Random transients, on the other hand, are often caused by Lightning and Electrostatic Discharge (ESD). Lightning and ESD generally occur unpredictably, and may require elaborate monitoring to be accurately measured, especially if induced at the circuit board level. Numerous electronics standards groups have analyzed transient voltage occurrences using accepted monitoring or testing methods. The key characteristics of several transients are shown in the table below. VOLTAGE CURRENT RISE-TIME DURATION Lighting 25kV 2kA 1 μs 1ms Switching 6V 5A 5μs 5ms EMP 1kV 1A 2ns 1ms ESD 15kV 3A <1ns 1ns Table 1. Examples of transient sources and magnitude Characteristics of Transient Voltage Spikes Transient voltage spikes generally exhibit a double exponential wave, as shown below for lightning and ESD. t1 Vp t2 Vp/2 Figure 1. Lightning Transient Waveform 1% 9% t The exponential rise time of lightning is in the range 1.2μsec to 1μsec (essentially 1% to 9%) and the duration is in the range of 5μsec to 1μsec (5% of peak values). ESD on the other hand, is a much shorter duration event. The rise time has been characterized at less than 1.ns. The overall duration is approximately 1ns. Why are Transients of Increasing Concern? Component miniaturization has resulted in increased sensitivity to electrical stresses. Microprocessors for example, have structures and conductive paths which are unable to handle high currents from ESD transients. Such components operate at very low voltages, so voltage disturbances must be controlled to prevent device interruption and latent or catastrophic failures. Sensitive microprocessors are prevelant today in a wide range of devices. Everything from home appliances, such as dishwashers, to industrial controls and even toys use microprocessors to improve functionality and efficiency. Most vehicles now also employ multiple electronic systems to control the engine, climate, braking and, in some cases, steering, traction and safety systems. Many of the sub- or supporting components (such as electric motors or accessories) within appliances and automobiles present transient threats to the entire system. Careful circuit design should not only factor environmental scenarios but also the potential effects of these related components. Table 2 below shows the vulnerability of various component technologies.

Transient Voltage Scenarios Electrostatic Discharge (ESD) Electrostatic discharge is characterized by very fast rise times and very high peak voltages and currents. This energy is the result of an imbalance of positive and negative charges between objects. ESD that is generated by everyday activities can far surpass the vulnerability threshold of standard semiconductor technologies. Following are a few examples: Walking across a carpet: 35kV @ RH = 2%;1.5kV @ RH = 65% Walking across a vinyl floor: 12kV @ RH = 2%;25V @ RH = 65% Worker at a bench: 6kV @ RH = 2%;1V @ RH = 65% Vinyl envelopes: 7kV @ RH = 2%;6V @ RH = 65% Poly bag picked up from desk: 2kV @ RH = 2%;1.2kV @ RH = 65% Lightning Induced Transients Even though a direct strike is clearly destructive, transients induced by lightning are not the result of a direct strike. When a lightning strike occurs, the event creates a magnetic field which can induce transients of large magnitude in nearby electrical cables. A cloud-to-cloud strike will effect not only overhead cables, but also buried cables. Even a strike 1 mile distant (1.6km) can generate 7 volts in electrical cables. Inductive Load Switching The switching of inductive loads generates high energy transients which increase in magnitude with increasingly heavy loads. When the inductive load is switched off, the collapsing magnetic field is converted into electrical energy which takes the form of a double exponential transient. Depending on the source, these transients can be as large as hundreds of volts and hundreds of Amps, with duration times of 4 milliseconds. Typical sources of inductive transients include: Generator Motor Relay Transformer These examples are common in electrical and electronic systems. Because the sizes of the loads vary according to the application, the wave shape, duration, peak current and peak voltage are all variables which exist in real world transients. Once these variables can be approximated, a suitable suppressor technology can be selected. The diagram at right V T shows a transient T 1 which is the result of 9% stored energy within the alternator of an V S automobile charging system. A similar transient can also be caused by other DC motors in a vehicle. For V B 1% VS = 25V to 125V V B = 14V T= 4ms to 4ms T 1 = 5ms to 1ms R =.5 to 4 example, DC motors power amenities such as power locks, seats and windows. These various applications of a DC motor can produce transients that are just as harmful to the sensitive electronic components as transients created in the external environment. t In a cloud-to-ground strike (as shown at right) the transientgenerating effect is far greater. This diagram shows a typical current waveform for induced lightning disturbances. PERCENT OF PEAK VALUE 1 9 5 1 O1 t t1 t2 TIME 3

TVS Diode Terms & Definitions Crowbar Device The class of suppressors that exhibit a crowbar characteristic is usally associated with 4-layer NPNP silicon bipolar devices or gas plasma/gdt devices. Upon reaching a threshold or breakover voltage, further increase in current flow will cause the device to rapidly conduct with only a few volts of forward drop. In essence, the line is momentarily short-circuited during the transient event. Operating Temperature Range The minimum and maximum ambient operating temperature of the circuit in which a device will be applied. Operating temperature does not allow for the effects of adjacent components, this is a parameter the designer must take into consideration. Capacitance The property of a circuit element that permits it to store an electrical charge. In circuit protection, the off-state capacitance is typically measured at 1 MHz with a 2V bias applied. Reverse Standoff Voltage (V R ) In the case of a uni-directional TVS diode, this is the maximum peak voltage that may be applied in the blocking direction with no significant current flow. In the case of a bi-directional transient, it applies in either direction. It is the same definition as Maximum Off-state Voltage and Maximum Working Voltage. Breakdown Voltage (V BR ) Breakdown voltage measured at a specified DC test current, typically 1mA. Usually a minimum and maximum is specified. Peak Pulse Current (I PP ) Maximum pulse current which can be applied repetitively. Usually a 1x1μs double exponential waveform, but can also be 8x2μs, if stated. Maximum Clamping Voltage (V C or V CI ) Maximum voltage which can be measured across the protector when subjected to the Maximum Peak Pulse Current. Peak Pulse Power (P PP ) Expressed in Watts or Kilowatts, for a 1ms exponential transient (see figure 1, page 23) it is I PP multiplied by V CL. TVS Diode Selection Checklist 1. Define Circuit Operating Parameters Normal operating voltage type in DC or AC: Device Type Required: Uni-drectional Bi-directional Normal operating voltage in volts: Maximum transient current (Ipp): Maximum clamping voltage (Vc): Required peak reverse surge power rating: Product mounting type (package): Operating temperature: 2. Narrow TVS Diode Series for the Application Please refer to the product selection charts and data sheets within this guide, factoring these key parameters: Reverse Standoff Voltage (V R ): The device V R should be equal to, or great than, the peak operating level of the circuit (or part of the circuit) to be protected. This is to ensure that TVS Diode does not clip the circuit drive voltage. Peak Pulse Current (I PP ): The Peak Pulse Current (I PP ) identifies the maximum current the TVS Diode can withstand without damage. The required I PP can only be determined by dividing the peak transient voltage by the source impedance. Note that the TVS Diode failure mechanism is a short circuit; if the TVS Diode fails due to a transient, the circuit will still be protected. Maximum Clamping Voltage (V C ): This the peak voltage that will appear across the TVS Diode when subjected to the Peak Pulse Current (I PP ), based on 1X1us exponential waveform. The V C of each TVS Diode is identified in each series data sheet electrical characteristics table. 3. Verify Ambient Operating Parameters Ensure that the application voltage is less than or equal to the device s standoff voltage, and that the operating temperature limits are within those specified by the device. 4. Verify Device Mounting Style and Dimensions Please refer to the dimension drawings contained within the data sheet of each series. 5. Test the Selected Device in Actual Application Please contact Littelfuse if you would like assistance with testing and verifying suitability of a Littelfuse device within your product.

Axial Leaded 6kA > AK6 series RoHS AK6 Series Description Agency Approvals The new AK6 series of high current transient suppressors have been specially designed for use in A.C. line protection and any demanding applications (AC or DC). They offer superior clamping characteristics over standard S.A.D. technologies by virtue of the Littelfuse Foldbak technology, which provides a clamping voltage lower than the avalanche voltage (but above the rated working voltage). Therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create very high capacity protection solutions.
