2 INTRODUCTION SEI ELECTRONICS / KEKO VARICON STRATEGIC ALLIANCE SEI ELECTRONICS and KEKO VARICON have formed a strategic alliance to jointly promote the sale of transient voltage suppression components throughout North America under a program called. The program combines a unique melding of leading-edge technological development, application engineering support and customer service designed to provide our customers with the best and broadest line of products and services in the industry. The products offered in the program include both multilayer and single layer varistors, packaged in EIA standard chip sizes and radial leaded configurations, which virtually cover every board level requirement for standard transient voltage protection. In addition, applications in market segments such as Automotive, Telecom Switches (Line Cards), Industrial & Motor Controls and AC Power Networks to name a few, are covered by specific product series designed for these unique transient voltage conditions. MULTILAYER PRODUCTS Low voltage multilayer varistors span a DC voltage range of 3.0 to 125 V DC, with energy ratings from 0.05 to 37.8 joules. The wide range of EIA chip sizes, 0603 to 3225, accounts for the exceptionally broad product offering (one of the most extensive in the industry), and radial leaded MLVs are a new addition to the family of TVS protection components. The combination of these devices addresses all but the most extremely damaging transients to semiconductors and/or integrated circuits from: (1) ultra-high voltage, low-energy ESD events, (2) ultra-high voltage, high-energy near lightning strikes, (3) relatively low-to-medium voltage, high-energy inductive load disruptions, and all transient environments in between. SINGLE LAYER PRODUCTS Low-to-medium voltage single layer (SLV) radial leaded discs, commonly known as MOVs, are designed primarily to operate in AC voltage applications. SEI s products are offered in AC voltages from 11 V to 550 V, energy ratings from 0.6 to joules and surge capabilities from 100 to 15,000 amps. Most applications are across AC power lines and protect against line surges generated from load switching, lightning and other forms of high-energy transient events. Please refer to the SEI/KEKO VARICON single layer catalog or contact SEI for any information related to SLV products. SPECIALTY PRODUCTS The SEI program embraces many specialty TVS products. Specific to the automotive industry, for example, the multilayer AV products offer exceptional electrical characteristics in much smaller packages and much higher levels of reliability than that achieved by typical automotive disc varistors. The multilayer OV (leaded) dual function component combines a low voltage varistor and capacitor into a single package for protection against voltage surges and RFI typically encountered in cars. KEKO VARICON HISTORY KEKO VARICON, headquartered in Zuzemberk, Slovenia, has produced over-voltage protection devices for over 10 years. In the late 80s, the company was acquired by Zoran and Angela Zivic from the former ISKRA Group and was named KEKO VARICON (VARI from VARIstor, and CON from CONdensator, the old term for a capacitor). The ISKRA Group, started in the mid 50s, had previously manufactured both single layer and multilayer ceramic electronic components. KEKO VARICON s General Manager, Zoran Zivic, has been actively involved in circuirotection developments in both active and passive components and material systems for more than 20 years. Mr. Zivic has written and published a wide variety of technical papers on electrical and electronic protection subjects and currently holds numerous product and material system patents. Considered one of the leading pioneers in developing surface mounrotection devices, Zoran Zivic has earned and maintains the role as a technological leader in this industry. GENERAL NOTES SEI s / KEKO VARICON products have been tested and approved under the following standards: UL1414, UL1449, CSA 22.2, IEC and CECC

17 ZVX Series Low Energy, Low Capacitance SMD Varistors Description The ZVX Series are low-energy (0.1 joules) varistor chips, designed specifically for the protection of I/O line drivers and other sensitive semiconductor gates from the damaging effects of high voltage, low-energy transients such as ESD events. Unlike other competitive low-energy varistors, however, the ZVX Series offers all the protection features of standard varistor chips, and exceptionally low values of capacitance. In these applications, as the frequency of data transfer increases, lower capacitance is required to eliminate possible skewing of the data signals due to capacitive loading. In most cases, the 1KHz capacitance values of the ZVX Series are less than one half that of the competition. Further, this series is offered in 0603, 0805 and 1206 sizes, with an expanded range of voltages from 3V to 38Vdc. The ZVX Series offers a circuit design engineer the greatest range of high-frequency, low-energy SMD varistor chips available in the marketplace today.

The MV Series incorporates a varistor function in the DC voltage range from 3V to 125V and the function of a high-frequency by-pass capacitor operating in the capacitance range from 10 nf to 1000 nf. They are intended for protection of all sensitive electronic devices experiencing both voltage transients and high-frequency noise produced by electromechanical devices such as buzzers, relays, etc. MV varistors/suppressors are square shaped components with in-line leads, which require at least 30% less mounting space than the two components they replace.
