Abstract
Among the mechanisms suggested to account for degradation of varistor materials, ion migration has strong support. Mobile, positively charge d ions in the depletion layer would be the key element in degradation. In this context, we discuss the consequences of an electrical stressi ng on the current-temperature characteristic of a commercial varistor.
