Varistors, or voltage-dependent resistors, are electronic components used to protect circuits and equipment from voltage spikes. The V18ZT2 is a device for transient voltage suppression, with a working voltage that is adjustable to suit the particular application. In this article, we will explore the application field and working principle of the V18ZT2.

What is the V18ZT2?

The V18ZT2 is a transient voltage suppressor, which protects electronic circuits from spikes in the electrical supply voltage. The transient suppressor is used in a wide variety of applications, from industrial and commercial to residential, and is suitable for use in a wide range of temperatures. The V18ZT2 provides transient voltage suppression of up to 1.2KV, with a maximum peak pulse current of 6A and a surge current rating of 14A.

V18ZT2 Working Principle

The V18ZT2 is designed to absorb the energy of peak voltage transients and protect electronic circuits from damage caused by overvoltage. When the voltage across the device exceeds the clamping voltage, the device will begin to conduct, dissipating the excess energy as heat. This reduces the voltage across the device to a safe level, in order to protect the electronic circuitry. The device features a high surge current rating, as well as a low leakage current and thermal dissipation.

The V18ZT2 works on the principle of avalanche breakdown, whereby a transient current passes through the device triggering an avalanche effect. When this occurs, holes and electrons are swept up and conducted through the device, dissipating the excess energy as heat and limiting the voltage drop.

V18ZT2 Application Field

The V18ZT2 has application in a wide variety of fields. It can be used to protect electronic circuits from overvoltage in automotive, industrial, and telecom applications. It is used in a range of electronics, including circuits for motor control, power conditioning, AC/DC converters, mobile phones, personal computers, and other consumer electronics. It is also used in power optimization and system reliability applications.

The V18ZT2 can also be used to protect delicate electrical components from transient surges and power spikes. In industrial and telecom applications, it is used to absorb the energy of lightning strikes and other high-voltage transients. In automotive applications, it is used to protect vehicles from the effects of shorts, spikes, and power surges.

In addition, the V18ZT2 is ideal for use in a wide range of temperatures, from -40°C to +105°C, and is suitable for both high voltage and medium-high voltage applications. Its adjustable working voltage ensures that it can be used to suit the particular application requirements.

Conclusion

The V18ZT2 is a reliable and efficient transient voltage suppressor, capable of providing protection from overvoltage and power surges. It is suitable for use in a wide range of applications, from automotive and industrial to telecoms and consumer electronics. Its adjustable working voltage, high surge current rating, low leakage current, and thermal dissipation make it a suitable choice for a variety of applications.
