AVX Multilayer Ceramic Transient Voltage Suppressors
GENERAL DESCRIPTION
TransGuard
®
multilayer varistors 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.
The increasing use of electronics technologies in all areas require reliable protection
against transient voltages that could damage the electronics circuitry as well as
EMI/RFI attenuation to prevent signal distortion and to meet regulatory requirements.
AVX TransGuard components help achieve both functions with single component.

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 cur-
rent. 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
®
tran-
sient voltage suppressors with 150Amp peak 8 x 20μS
waveforms shows negligible degradation in breakdown
voltage and minimal increases in leakage current.
