## **StaticGuard AVX Multilayer Ceramic Transient Voltage Suppressors ESD Protection for CMOS, Bi Polar and SiGe Based Systems** 

## **GENERAL DESCRIPTION** 

The StaticGuard Series are low capacitance versions of the TransGuard and are designed for general ESD protection of CMOS, Bi-Polar, and SiGe based systems. The low capacitance makes these products suitable for use in high speed data transmission lines. 

## **GENERAL CHARACTERISTICS** 

- Operating Temperature: -55ºC to 125ºC 

- Working Voltage: ≤ 18Vdc 

- Case Size: 0402, 0603, 0805, 1206 

## **FEATURES** 

- Typical ESD failure voltage for CMOS and/or Bi Polar is ≥ 200V 

- Low capacitance (<200pF) is required for high-speed data transmission. 

- Low leakage current (IL) is necessary for battery operated equipment. 

## **APPLICATIONS** 

   - •Sensors 

   - CMOS 

   - SIGe based systems 

   - Higher speeed data lines 

   - Capacitance sensitive applications and more 

- 15kV ESD pulse (air discharge) per IEC 61000-4-2, Level 4, generates < 20 millijoules of energy.

## **StaticGuard** 

## **AVX Multilayer Ceramic Transient Voltage Suppressors** 

## **TYPICAL PERFORMANCE CURVES (0402 CHIP SIZE)** 

## **VOLTAGE/CURRENT CHARACTERISTICS** 

Multilayer construction and improved grain structure result in excellent transient clamping characteristics up to 20 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 150Amp peak 8 x 20μS waveforms shows negligible degradation in breakdown voltage and minimal increases in leakage current.
