Simple Model of Metal Oxide Varistor for Pspice Simulation
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2004Metal oxide varistors (MOVs) are commonly used to suppress transients in many applications, such as industrial process measurement and control instrumentation, when exposed to electromagnetic interference. Varistors symmetrical, sharp breakdown characteristics enable them to provide transient suppression performance.

The physics of metal oxide varistors
Journal of Applied Physics, 1975This paper outlines our present understanding of the conduction mechanisms and physical processes relevant to the performance of ZnO−based ceramic varistors. Varistor behavior is determined by the gross ceramic microstructure of the device as well as by the localized conduction processes which occur between grains. We show that the qualitative features

ac properties of metal-oxide varistors
Journal of Applied Physics, 1976Measurements of the small-signal ac response of ZnO-based ceramic varistors are reported for frequencies f in the range 30<f<108 Hz and temperatures T in the range −200<T<300 °C. The high effective varistor dielectric constant results from the device microstructure with no detectable electrode contribution.

Thermal Runaway in Metal Oxide Varistors
MRS Proceedings, 1981ABSTRACTThe conditions leading to thermal runaway in metal oxide varistors are discussed in terms of its power dissipation. An equivalent circuit is used to rationalize the similarities and differences between the DC and 60 Hz ac behavior.
