TVS - Varistors, MOVs are also known as Transient Voltage Suppression (TVS) devices. They are designed to protect sensitive electronics from high-voltage transients and surges. The V421HF34 is a varistor device with a peak power rating of 800 watts.

The V421HF34 is a surface mounted varistor device designed for reverse protection of sensitive electronic components. It is composed of a ceramic substrate and an array of metal-oxide varistors (MOVs). The MOVs are connected in series and can withstand very high voltages and currents, up to 1,200 volts and 33 amperes. The device also provides high-level overvoltage protection up to 2,000 volts.

The working principle of the V421HF34 is simple. When a voltage is applied to the device, it conducts a large amount of current. This current is then dissipated as heat, which is then absorbed by the varistor material. This reduces the voltage across the MOVs and provides protection against overvoltage.

The V421HF34 is mainly used in the automotive industry. It can be used to protect electronic modules such as ignition systems, ECUs, and power steering systems from overvolts. The device is also used in consumer electronics and home appliances such as TVs, air conditioners, and refrigerators. It provides protection against voltage spikes that could damage sensitive electronic components.

The V421HF34 can also be used in industrial applications. It provides overvoltage protection for motor control systems, industrial robots and process control systems. It is also used in medical devices, military systems and communication systems. The device is also used to protect power supplies and UPS systems from overvoltage.

The V421HF34 is a reliable and cost effective TVS device. It provides high-level overvoltage protection and can be used for a variety of applications. Its compact size and light weight make it suitable for use in automotive and industrial applications. It is a popular choice for protection of sensitive electronic components from overvoltage.
