A varistor is an electronic component that is used to protect electronic devices from overvoltage surges. It is also known as a voltage-dependent resistor (VDR) or a metal-oxide varistor (MOV).
The basic structure of a varistor consists of a ceramic or metal oxide material with a nonlinear resistance characteristic. When the voltage across the varistor reaches a certain threshold, its resistance decreases sharply, allowing a large current to flow through it and diverting the excess voltage away from the device it is protecting.
Varistors are commonly used in electronic circuits to protect against power surges, lightning strikes, and other voltage spikes that can damage sensitive components. They are also used in power distribution systems, where they help to protect transformers, motors, and other equipment from overvoltage events.
There are two main types of varistors: silicon carbide (SiC) and zinc oxide (ZnO). SiC varistors are commonly used in high-power applications, such as power distribution systems and industrial equipment, while ZnO varistors are used in lower power applications, such as consumer electronics and telecommunications.
