TransGuard
AVX Multilayer Ceramic Transient Voltage Suppressors
TYPICAL PERFORMANCE CURVES
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.

INSERTION LOSS CHARACTERISTICS
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
sient voltage suppressors with 150Amp peak 8 x 20μS
waveforms shows negligible degradation in breakdown
voltage and minimal increases in leakage current. This
does not mean that TransGuard
degradation, but it occurs at much higher current.
