TVS - Varistors, MOVs, is a class of electronics components who are used for providing surge protection and to minimize voltage transients. A 2859563 application field and working principle are two important concepts for understanding the functions of these electronics components.

Application Field

TVS - Varistors, MOVs, are very versatile and can be used in many applications. Generally, they are used to protect electronics devices from voltage transients caused by power surges, lightning strikes, or even electrostatic discharges. TVSs are also used in the electronics industry for AC line filtering. They are often used in power supplies and touchscreen systems. In some cases, they are used to reduce radio-frequency interference as well.

Furthermore, these electronics components are also utilized in the automotive industry, for power supply systems or for automotive audio systems. A variety of mobile devices also use TVSs or MOVs in their power systems, to provide protection against power surges and other types of transients.

Working Principle

The working principle of TVS - Varistors, MOVs, is based on two concepts: voltage breakdown and electro-mechanical hysteresis. When a voltage transient happens, the voltage in the circuit will increase rapidly, potentially damaging the components. The voltage breakdown of the TVS is then triggered and the current is diverted away from the device, saving it from the damaging effects of the transient.

The electro-mechanical hysteresis is a key component of the protection mechanism of TVSs. It works by allowing a small amount of current to pass through the TVS during low-level transients. Then, as the voltage reaches the required threshold, the capacitive element of the TVS is activated and the current is diverted away from the device.

Conclusion

TVS - Varistors, MOVs, are essential components in electronics designs as they help to protect sensitive devices from damage caused by power surges and other voltage transients. The application of TVSs is quite versatile and they can be found in a variety of devices ranging from mobile devices to power supplies and touchscreen systems. The working principle of TVSs is based on the concept of voltage breakdown and electro-mechanical hysteresis, which allow the device to divert the current away from the device and protect it from voltage transients.
