Degradation in ZnO varistors

Journal of Physics: Condensed Matter, 1993
Among the mechanisms suggested to account for degradation of varistor materials, ion migration has strong support. Mobile, positively charged ions in the depletion layer would be the key element in degradation. In this context, the authors discuss the consequences of an electrical stressing on the current-temperature characteristic of a comment ...

Time Dependence of Degradation in ZnO Varistors

physica status solidi (a), 1982
Starting from the results of a previous paper on the functional relationship of the degradation of ZnO-varistors and the influence factors (especially U, I,T) an equation system is derived to describe the time-dependence of the degradation. The solutions including the contribution of degradation-, recovery- and increasing effects of currents and ...

Thermal breakdown in ZnO-varistor ceramics

Physica Status Solidi (a), 1980
Thermal breakdowns representing an essential mechanism for the lifetime limitation of ZnO-varistor ceramics are characterized with respect to the parameters of the breakdown point (especially breakdown temperature Tb) (for 21 °C as ambient temperature: Tb = 174 °C).
