Registered in England and Wales. Number 8860726. Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have electrical characteristics similar to back-to- back Zener diodes. Voltage TransientsVaristors feature high durability, which is essential for withstanding repeated high-peak pulse currents and high-energy surge transients. They also offer a wide voltage range, high energy absorption, and fast response to voltage transients. Peak current ratings range from 20 to 70,000 A, while peak energy ratings range from 0.01 to 10, 000 J. In this context, “voltage transients” are defined as short-duration surges of electrical energy. In the electrical or electronic circuits that varistors intend to protect, this energy may be released either in a predictable manner via controlled switching actions, or randomly induced into a circuit from external sources.
