TVS - Varistors, MOVs, 82551200 Application Field and Working Principle

The 82551200 is a voltage variable resistor or Transient Voltage Suppressor (TVS), suitable for replacing surface mount varistors and MOVs in automotive applications. The 82551200 is designed to be used in high voltage automotive applications. It has an operating voltage range of up to 12V and can be used in a wide variety of applications.

A varistor is a voltage-dependent resistor (VDR) used mainly to protect circuits from overvoltage transients. They are made from a variety of materials such as zinc oxide, silicon carbide, and multilayer ceramic composites. Varistors offer simple protection against overvoltage transients and fast turn-off and excellent frequency and energy handling capabilities. These components are used in overvoltage protection circuits, EMI suppression, and snubbers.

An MOV (metal oxide varistor) is also a voltage-dependent resistor (VDR) that is specifically designed for better clamping performance and overvoltage protection. MOVs are composed of zinc oxide pellets with a metal coating on the surface that helps them respond more quickly to voltage transients. These components are mainly used in overvoltage protection circuits and EMI suppression.

The 82551200 is designed to be used in automotive applications where high voltage and fast turn-off times are required. It is an ideal replacement for traditional varistors and MOVs in high voltage and automotive applications. The 82551200 can be used in applications up to 12V and is designed to offer high clamping performance and fast turn-off times.

The 82551200 operates on the principle of a voltage-dependent resistor (VDR). When a voltage transient, such as an electrostatic discharge (ESD), passes through the 82551200, the VDR is triggered and the voltage is clamped. The 82551200 is designed with a high voltage breakdown threshold, fast turn-off time, and excellent energy handling capabilities.

The 82551200 is typically used in automotive applications such as EMI suppression, load switches, and relay drivers. It is also used in variable voltage dc power supplies, power inverters, and dc to dc converters. Its excellent frequency and energy handling capabilities make it an ideal solution for automotive applications.

The 82551200 is an ideal device for automotive applications requiring fast turn-off times, high voltage protection, and EMI suppression. Its high voltage breakdown threshold, fast turn-off time, and excellent energy handling capabilities make it an ideal choice for a wide variety of applications. The 82551200 is a reliable and robust device that is designed to provide excellent protection in automotive applications.
