TVS (Transient Voltage Suppressors) are a class of devices typically used in the protection of electrical and electronic systems from the effects of transient overvoltage conditions. The MOV (Metal Oxide Varistor) is a non-linear, voltage-dependent resistor, designed to provide a high level of transient overvoltage protection. The V180ZT05PX2855 is one of the most popular TVS and MOVs on the market today, and is used in a variety of applications. In this article, we will discuss the application field and working principle of the V180ZT05PX2855.

The V180ZT05PX2855 is designed for protection against high-voltage transients in both AC and DC lines. Its maximum surge current rating is 1.4 kA (8/20μs), and its response time is less than 5 ns. It can withstand surge voltages up to 5500 V. The V180ZT05PX2855 is made up of three layers of zinc oxide varistors, providing a high degree of robustness and reliability. The V180ZT05PX2855 is ideal for a wide range of applications, including power supplies, motors, LEDs, Ethernet systems, communication systems, and more.

The working principle of the V180ZT05PX2855 is quite simple. When a voltage transient occurs, the zinc oxide varistors become conductive and begin to reduce the voltage level, preventing the system from being damaged. It does this by absorbing the energy from the transient and dissipating it as heat. Since the device is made up of three layers of varistors, the device is able to absorb more energy than a single layer device, providing better protection against surge voltages. The device functions as a kind of \'voltage limiter\', preventing the voltage from exceeding the preset levels.

In addition, the V180ZT05PX2855 has a positive temperature coefficient which helps prevent thermal runaway. This means that as the temperature of the device increases, the device will automatically become more resistant and reduce the amount of energy being dissipated as heat. This helps protect the device from overheating and provides a greater level of protection against voltage transients.

Overall, the V180ZT05PX2855 is one of the most reliable TVS and MOVs on the market today. It is designed for a wide range of applications, provides excellent protection against surge voltages, and has a positive temperature coefficient for thermal protection. Thanks to its robust and reliable design, it is the ideal choice for protecting electrical and electronic systems from the dangerous effects of transient overvoltage conditions.
