TVS diode, or transient voltage suppressor, is a component that helps to provide protection against voltage transients. The V68ZT3PX2855 is a varistor, or MOV (Metal Oxide Varistor). It is used for transient voltage suppression in various applications. In this article, we will discuss the application fields and working principle of the V68ZT3PX2855.

Varistors, or MOVs, are overvoltage suppression components that use Metal Oxide Varistors to provide protection against overvoltage conditions. The V68ZT3PX2855 is a 1500W UL1449 rated MOV designed for high temperature (up to 250°C) and high surge voltage (up to 5kV) applications. It is also UL7768 listed.

V68ZT3PX2855 Application Fields and Working Principle

The V68ZT3PX2855 is designed for use in electrical and electronic equipment exposed to voltage transients. Common applications include power supplies, communication equipment, and other industrial and commercial applications. It is also suitable for use in industrial and automotive environments.

The V68ZT3PX2855 is a varistor, or MOV, designed to suppress voltage transients. This is accomplished through a combination of thermal, mechanical, and electrical characteristics. When a voltage transient occurs, the MOV acts like an open circuit, allowing the voltage to rise to its maximum level. As the voltage rises, the MOV starts to dissipate the energy, releasing it in the form of heat. In this way, the MOV helps to limit the amount of energy that gets transferred to the circuit.

The MOV is designed to have a low impedance over a wide frequency range, allowing it to quickly clamp the rising voltage. The MOV also has a high current rating, allowing for large transient currents to be clamped without any damage. Furthermore, it has a minimum clamping voltage of 10V and a maximum clamping voltage of 600V.

The V68ZT3PX2855 also features a built-in thermal sensing mechanism. This sensing mechanism will detect when the ambient temperature of the MOV is too high, and it will reduce the clamping voltage to prevent thermal damage. The thermal sensing mechanism also has an adjustable setting, allowing the user to customize the maximum temperature of the device.

In summary, the V68ZT3PX2855 is a high temperature MOV designed for use in industrial and automotive applications. It is designed to protect circuits from overvoltage transients by clamping the incoming voltage and dissipating the energy in the form of heat. It also has a built-in thermal sensing mechanism that can be adjusted to the desired temperature.
