TVS - Varistors, MOVs, are designed to protect against transient electrical surges. The specific type of protection provided by these devices is usually written on the specification sheets. But it is important to know what kind of protection that can be provided by a specific type of TVS in order to properly use them in an application. The following article will explain the application field and working principle of the V56ZU20P.

The V56ZU20P is a radial-leaded bidirectional MOV (Metal Oxide Varistor). It is designed to provide superior protection against transient voltage spikes. The device is also capable of handling high currents, making it ideal for protecting sensitive electronic components from of transient voltages. The V56ZU20P is also designed to work over a wide temperature range, making it suitable for use in a wide variety of applications.

The application field of V56ZU20P is mainly in the field of lightning and surge protection. The device is most often used in the lightning protection of communication equipment, personal computers, power supplies, etc. It can also be used in medical equipment that requires lightning protection in order to provide safe operation and reduce the risk of failure. Additionally, the device is suitable for automotive surge protection, especially on the power supplies within electrical and electronic systems.

The working principle of the V56ZU20P is based on the resistance voltage relationship of a varistor. The device is composed of two main parts, which are the outer shell and an inner block. The outer shell consists of two metal parts, while the inner block is made of metal oxide materials. When a voltage is applied to the device, the metal oxide materials will resist the flow of electric current, thus limiting the voltage spike applied to the circuit.

The V56ZU20P will offer protection against transients up to 500µs long. This provides enough time even for very high voltage spikes to be absorbed and dissipated by the device, while relatively short transients will be intercepted before reaching the protected circuitries. The MOV also provides protection against voltages up to 850Vac, which is suitable for most applications.

The V56ZU20P also features a current rating of 25A/150A, which is suitable for most applications. Additionally, the device can be reverse mounted, which allows it to be placed in tight spaces, making it highly suitable for applications where space is a critical factor. The device also has a slender construction, which reduces the risk of mechanical stress.

In conclusion, the V56ZU20P is designed to protect against transient electrical surges and is suitable for applications in the field of lightning and surge protection. Its high current rating and narrow construction make it suitable for applications which require space efficient solutions. Its reverse mount further increases its versatility and allows it to be used in more difficult applications. Furthermore, its wide operating temperature range makes it suitable for use in a wide variety of applications.
