PULSE DEGRADATION
Traditionally varistors have suffered degradation of electrical perfor-
mance 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

150 Amp peak 8 x 20μS waveforms shows negligible degradation
in breakdown voltage and minimal increases in leakage current.
This does not mean that TransGuard
