Varistors are used to protect semiconductors against voltage overload. They play a major role in high voltage transmission applications. They protect high voltage equipment from lightning, over voltage and surge voltage. The most common is the MOV (metal-oxide varistor). This type of varistor contains a ceramic mass of zinc oxide grains, in a matrix of other metal oxides (such as small amounts of bismuth, cobalt and manganese) sandwiched between two metal plates.
