MOV is the most commonly used type of varistor. It is called so as the component is made from a mixture of zinc oxide and other metal oxides like cobalt, manganese and so on and is kept intact between two electrodes which are basically metal plates. MOV’s are the most used component to protect heavy devices from transient voltages. A diode junction is formed between each border of the grain and its immediate neighbour. Thus an MOV is basically a huge number of diodes that are connected parallel to each other.  They are designed to be in the parallel mode as it will have better energy handling ability. But, if the component is meant for providing better voltage rating, it is better to connect them in series.

Metal oxide varistors are a common component in electronic equipment. They are made from a mixture of zinc and an oxide material, such as titanium dioxide. Varistors work by dissipating energy when they are overloaded. MOVs are important because of http://www.lignum.vsi.ru/index.php?nma=forumd&fla=topic&forum=1&ids=1274 they can protect against electrical short circuits.
