MOV Performance. This varistor mainly performs as a line voltage surge suppressor. It doesn’t conduct electricity when the voltage across it is lesser than the clamping voltage. However, the MOV won’t perform if it receives a surge spike rating higher than the varistor can handle. The result of this is a damaged MOV.Metal Oxide Varistors (MOV) Metal Oxide Varistors Referred to as MOV, or Varistor.

For example, suppose it's an SMPS device with a max capability of 285V RMS from the .
Production of holes in semiconductor crystal. If you supply heat to a semiconductor crystal, electrons absorb heat energy and get excited. After getting a sufficient amount of energy, electrons jump to the conduction band from the valence band. As a result, vacant places arise in the valence band due to the absence of those electrons.
