TVS – Varistors, MOVs are components used in manufacturing of electronic circuits. Varistors are two terminal devices mainly used to provide protection from overvoltage conditions. The B72205S0151K211 is a varistor used in a wide range of applications. This device is particularly suited for industrial, home and building automation to protect from high voltage transients.

A varistor is a voltage-variable resistor and is mainly used for suppression of surge voltage. B72205S0151K211 is a surface mount varistor which offers high surge withstand capability with superior thermal stability and endurance, offering overvoltage/surge protection from transient voltages. It is a low capacitance silicon based varistor capable of absorbing up to 420A 10/1000μs current pulse without failure.

The working principle of the B72205S0151K211 is that it has a voltage-dependent resistance. The resistance of the device is very high when it is connected between two voltage points. But when a voltage exceeding a certain threshold is applied, the B72205S0151K211 works by reducing the voltage to a safe value. This ensures that the voltage across the device does not exceed the threshold, preventing damage to other components.

The typical application fields of the B72205S0151K211 are found in a wide range of industrial, home and building automation projects. It can be used for EMI/RFI line filtering, noise suppression, overvoltage/surge protection, and lightning protection. It is usually used in conjunction with other protection devices such as fuse or trip switches, and can also be used in conjunction with AC line voltages. It is an ideal device for protection in automotive applications, HVAC systems, solar panels, UPS systems, and others.

The B72205S0151K211 is a reliable, high performance surface mount varistor with excellent performance characteristics. It is a suitable device for overvoltage/surge protection applications and offers superior protection from transients and noise. It is an excellent choice for projects requiring a reliable and compact varistor with high voltage threshold and capacitance tolerance.
