TVS - Varistors, MOVs

ZV35K2220T102N is a part of varistors, MOVs class. Varistors, which stands for variable resistors, and MOVs, which stands for metal oxide varistor, are both two-terminal nonlinear circuit components for directly limiting voltage surges with a high clamping voltage, low leakage current, excellent surge response time, and high energy-dissipating capacity.

Application Field

ZV35K2220T102N is typically used in consumer products, such as computers, audio-visual equipment, and hand-held electronic products. It could also be used in other fields as well, such as mobile devices, AC/DC adapters, heavy industrial equipment, power supplies, and automotive electronics.

MOV and varistor can both be used for shielding against electrostatic discharge, surges, and electrical transients. They are also used to guard devices against voltage spikes, lightning strikes, and power outages. In particular, MOVs are mostly used for protecting sensitive electronics from instant high voltage, while varistors are often used to protect against lower voltage transients.

Working Principle

When an MOV is subject to a voltage higher than the rated voltage, the resistor will enter the nonlinear region within it, meaning a drastic drop of resistance. This will cause the current to become extremely high, so that the increased current will flow through the resistor and thus reduce the voltage to the practical device.

When a varistor is subject to a voltage higher than the zinc oxide material\'s breakdown field, the varistor will enter the nonlinear region within it, meaning a drastic decrease in resistance. This will cause the current become extremely high, so that the increased current will flow through the resistor and thus reduce the voltage to the practical device.

MOV and varistor both have an excellent clamping voltage, low leakage current, excellent surge response time, and high energy-dissipating capacity. Since they both have these features, they will both work well to protect electronics from voltage spikes.

Conclusion

ZV35K2220T102N is a part of varistors, MOVs class, and is typical used in consumer products. It\'s working principle is that when subject to a voltage higher than the rated voltage, it will enter the nonlinear region within itself, meaning a drastic decrease in resistance. This will cause the current become extremely high, so that the increased current will flow through the resistor and thus reduce the voltage to the practical device. MOV and varistor both have an excellent clamping voltage, low leakage current, excellent surge response time, and high energy-dissipating capacity.
