TVS varistors, MOVs are components used to protect circuits from overvoltage. A V27ZC2P varistor is a type of member of the TVS-Varistors family. It has components of two breakdown elements, with clamping action for when transient voltage is too high, which will damage other basic circuits.

The working principle of the V27ZC2P is simple. It is composed of two breakdown elements, typically metal oxide varistors and avalanche diodes. The clamping action of the two components provides protection against overvoltage from transient voltage changes. The two components work together to provide an overvoltage protection.

A metal oxide varistor is a semiconductor device which consists of a metal film with zinc oxide or some other type of non-magnetic material placed on the terminal. It is a non-linear resistor which can absorb large amounts of energy. When the input voltage exceeds the breakdown or clamping voltage of the varistor, the varistor immediately begins to conduct current, limiting the voltage to the clamping voltage.

The avalanche diode is used to provide a low resistance path for the current created by the input voltage exceeding the breakdown voltage of the metal oxide varistor. The avalanche diode quickly absorbs the energy created in order to prevent damage to other components. When the avalanche diode absorbs the energy, it generates a lower breakdown voltage which is less than the input voltage. This lower voltage clamping limits the voltage across the other components.

The V27ZC2P is available in either a surface mount or through-hole package and is designed for applications with a breakdown voltage of 27V DC. It is designed to handle up to 1.7 Seconds of energy and offers fast response time. The V27ZC2P is a low-cost solution for overvoltage protection in consumer and industrial applications. It is widely used in a variety of applications including automotive electronics, consumer devices, power supplies, and telecommunications equipment.

In conclusion, the V27ZC2P varistor is a member of the TVS-Varistors family, with two breakdown elements that offer protection from overvoltage. Its working principle is fundamental to the V27ZC2P\'s design, as it utilizes both metal oxide varistors and avalanche diodes to provide fast, reliable protection in a variety of applications.
