TVS - Varistors, MOVs

TVS stands for Transient Voltage Suppressor, a type of semiconductor device designed to protect other components from a surge in voltage. Varistors, Metal Oxide Varistors (MOVs) and Zener diodes are the three main types of TVS. The B72220Q0211K101 is a varistor that is used to protect components from overvoltage.

Application Field of the B72220Q0211K101 Varistor

A varistor is a semiconductor device with a high resistance that changes with the applied voltage. This type of TVS can provide protection against overvoltage and minimize the risk of electrical failure or short circuit in a system. The B72220Q0211K101 is a type of varistor that is used in a variety of applications, from power supplies to lighting fixtures, industrial equipment, consumer electronics, and automotive equipment.

This varistor features high voltage rating (2200V), low leakage current (0.1uA) and low clamping voltage (11V). This makes it an ideal choice for use in applications where overvoltage needs to be prevented, such as in electrical equipment, control systems, and automotive systems.

Working Principle of the B72220Q0211K101 Varistor

The B72220Q0211K101 is a type of varistor, which is a semiconductor device designed to protect components from overvoltage. It works by changing its resistance when the applied voltage increases. If the applied voltage is above its breakdown voltage, the varistor will become a low-impedance path, allowing current to flow freely and preventing excess voltage from reaching the protected components. In normal conditions, the varistor behaves as an open circuit with a very high impedance, blocking current from passing.

The varistor also has the ability to act as a noise filter, reducing electromagnetic interference (EMI) and radio frequency interference (RFI). This helps reduce the noise caused by the components protected by the varistor and allows the system to operate more reliably.

Conclusion

The B72220Q0211K101 varistor is a type of TVS designed to protect components from overvoltage. It has a high voltage rating, low leakage current and low clamping voltage, making it an ideal choice for a variety of applications. It also has the ability to act as a noise filter, helping reduce the noise generated by components and improving system reliability.
