Abstract
Several new results on the electrical breakdown properties of ZnO‐based ceramic varistors are presented. A second‐breakdown phenomenon associated with thermal runaway and characterized by a negative differential conductivity was observed in dc tests. The curve of capacitance versus bias current exhibited hysteresis while the I‐V characteristics became nonsymmetric and showed rectification after second breakdown.This publication has 9 references indexed in Scilit:
