TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are two important options when it comes to surge protection. While they have some similarities – both are designed to divert extra energy away in case of a spark or an electrical surge, they have significant differences as well. The V150ZU20PX2855 is one of the most common types of TVS - Varistors, and it has a wide range of applications and uses. This article will discuss the application field and working principle of the V150ZU20PX2855.

The V150ZU20PX2855 is a transient voltage suppressor designed to protect against power surges and other overvoltage conditions. The device is based on the varistor technology, which is basically a voltage-controlled variable resistor. When exposed to a voltage higher than the specified voltage rating, the varistor will act as a short circuit, allowing the current to flow freely and diverting it away from the equipment it was protecting.

The V150ZU20PX2855 is designed to work in both AC and DC circuits. It has a voltage rating of 150V, a peak energy rating of 20 Joules, and a peak pulse current rating of 85A. The dielectric strength of the device is 4kV and the operating temperature range is -40 to 80C. It is a surface-mounted device and has an exponential voltage-temperature coefficient.

The V150ZU20PX2855 is a versatile device that can be used in a variety of applications. In AC circuits, it is commonly used in surge protection, lightning protection, and arc fault protection. In DC circuits, it can be used for overvoltage protection, load dump protection, and Polarity Reversal Protection (PPR). It can also be used in audio applications, such as loudspeakers, audio power amplifiers, and DVD players.

The working principle of the V150ZU20PX2855 is quite simple. When exposed to a voltage higher than the rated voltage, the device will act as a short circuit, allowing the current to flow freely and diverting it away from the equipment it was protecting. In this way, the device is able to protect against power surges, lightning strikes, and other overvoltage conditions.

In conclusion, the V150ZU20PX2855 is a versatile and reliable device designed for surge protection applications. It has a wide range of applications, including AC and DC circuits, as well as audio applications. The working principle of the device is based on the varistor technology, which acts as a short circuit in the presence of a higher-than-rated voltage.
