Varistor basics


The metal oxide varistor, MOV, has a characteristic where for low voltages it has a high electrical resistance, and for higher voltages the resistance falls. Unlike diodes, the metal oxide varistor exhibits in both polarities

There are two main types of varistor:

Ceramic / metal oxide varistor:   When the term varistor is used, this is generally what is being referred to. The varistor is bidirectional and is based around a ceramic or metal oxide.

Diode varistor:   This type of structure utilises a diode whose turn on characteristic provides the variable resistance. If only a single diode is used, then it only acts in one direction, but obviously back to back diodes can be used to provide bidirectional variable resistance properties. Normally when diodes are used for protection they are not normally referred to as varistors, although this may sometimes be the case.
