TVS - Varistors, MOVs: Application field and working principle

Varistors, which are sometimes referred to as Voltage Dependent Resistors (VDRs), and Metal Oxide Varistors (MOVs) are two-terminal solid state components that protect electrical circuits from damaging voltages by providing an alternative path for the excess current within the circuit. These devices, which are commonly used in the design of circuits subjected to various levels of overvoltage protection, are available in a wide variety of configurations and ratings to meet the needs of almost any application.

Application Fields

Varistors and MOVs are commonly found in a variety of industries and applications, including electrical and electronic equipment, consumer electronics, automotive and aerospace, medical products, and telecommunications. Varistors and MOVs are often used to provide protection against electrical transients and surges, voltage overshoot, voltage sag, and voltage dropouts. They can also be used to increase the signal-to-noise ratio in low-power communication lines and minimize the risk of permanent equipment damage by protecting the connected side of the device from excessive voltage, which can cause permanent damage to the equipment and can even cause fires.

In many applications, Varistors and MOVs are combined with transformers, capacitors, and resistors to create a comprehensive protection circuit. This type of protection circuit is typically designed to absorb the high-voltage transients and dissipate them before they can cause any damage. In addition, the circuit can provide other forms of protection, such as limiting the duration and peak levels of an incoming transient.

Working Principle

Varistors and MOVs are typically composed of a ceramic material or a mixture of two or more ceramic materials that are formed into a disc and coated with a thin metal film on both sides. When these devices are exposed to a voltage in excess of their "breakdown" or "clamping" voltage, they act as an ideal diode and allow uninterrupted conduction of the excess voltage, thus providing an alternative path for electric current flow. The benefit of this action is that it prevents permanent damage to a circuit from excessive voltages.

Varistors and MOVs typically have a grading system of shorthand notations that provide the user with information about the device\'s performance characteristics. For example, a grading of VP1MHEA indicates that the device has a clamping voltage of 1V and a maximum dissipation of 0.25W, as well as an energy rating of 6J. This information helps the designer to choose the correct device for the application, based on the voltage and current requirements of the circuit.

Conclusion

Varistors and MOVs are essential components for protecting electronic circuits. They are available in a variety of configurations and ratings to meet the needs of different applications, and are typically combined with transformers, capacitors, and resistors to create a comprehensive protection circuit. Varistors and MOVs have a grading system of shorthand notations that provide information about the device\'s performance characteristics, allowing the designer to choose the correct device for the application based on voltage and current requirements.
