A Varistor, also known as a Metal Oxide Varistor (MOV), is a voltage-dependent variable resistor (VDR) that is commonly used to protect circuits and semiconductor devices from overvoltage, overcurrent, and overheat. The V20H230P is a type of Varistor that is made from zinc oxide and is designed to provide exceptional protection from transient voltage spikes.

Varistors are typically used in applications such as power line commoning, surge protection, ESD protection, and surge suppression. They provide isolation from transient voltages by using a combination of high capacitance per unit area, high leakage resistance, and low breakdown voltage. The V20H230P is a wide gap version of the Varistor and is mainly used for high-voltage surge protection applications.

In operation, the Varistor works by clamping voltage to protect the underlying circuitry, and by dissipating energy when a voltage exceeds the designed breakdown voltage. It absorbs the voltage above the level at which it can no longer provide protection and passes an equal but positive voltage to ground, supplying insulation to the equipment it is connected to. This process limits the peak voltage of a transient surge, which helps ensure that the integrated circuit it is connected to remains protected.

The V20H230P Varistor has a clamping voltage of (Vc) 280V, a rated voltage of (Vv) 210V and a breakdown voltage of (Vbr) 370V. Its rated dissipation power is (Pt) 11W and operating current is (Is) 0.1A. It is capable of providing protection against overvoltage, over-current and surge voltage, and is suitable for applications such as switch mode power supplies, smart grids, medical equipment, data communications and industrial control systems. The Varistor is designed to ensure that it does not exceed 180°C while dissipating power, which ensures that it is highly reliable when used in such applications.

The V20H230P Varistor is an important component for an efficient and safe electrical system and is highly recommended as it provides exceptional protection against surges and overvoltage conditions. It is also one of the most affordable and efficient ways to protect electronic devices from the damage caused by overvoltage conditions.
