Simple Model of Metal Oxide Varistor for Pspice Simulation

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2004
Metal 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.

Recycling zinc oxide varistor blocks for electro‐active silicone composites

International Journal of Applied Ceramic Technology, 2017
The recycling process toward the elimination of varistor wastes into new electro-active silicon composites has been investigated. We studied the dependence of the E-J characteristics on the aggregate content in the polymer matrix.

The physics of metal oxide varistors

Journal of Applied Physics, 1975
This 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, 1976
Measurements 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, 1981
ABSTRACTThe 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.

Pressure effects on metal oxide varistors

Applied Physics Letters, 1976
Preliminary results on the strong dependence of current-voltage characteristics of ZnO-based metal oxide varistors on pressure up to ∼5 kbar (nominal) are reported. This letter perhaps constitutes the first pressure study on electronic ceramics.
