A varistor is an electronic component with voltage-dependent resistance properties. It is commonly referred to by one of its trade names, such as metal-oxide varistor (MOV) or transil diode. The V575LC80CP is a type of varistor. The V575LC80CP is an unidirectional metal-oxide varistor (MOV), specifically designed for use in power supplies and lightning-protecting applications. It has been designed to provide protection from transient overvoltages and lightning strikes by providing a low resistance path to ground.

The V575LC80CP is a three-terminal, encapsulated, board-mounted, cylindrical metal-oxide varistor with a peak AC voltage rating of 400 volts and a DC holding voltage rating of 500 volts. The unit has a rated current of 275 amps, a peak pulse current of 100 amps, and a minimum energy response time of 10 microseconds. The clamping voltage of this device is 80 volts.

The main application field of V575LC80CP is in transient voltage surge suppressors (TVSS), also known as surge protectors. It is used in devices such as power strips, appliances, computers, and other electrical equipment in order to provide protection from power surge events and spike voltages. The V575LC80CP is also often used in grounding applications. It provides a low resistance path to ground, which allows current to be safely and effectively directed away from protected equipment.

The working principle of V575LC80CP is based on its voltage-dependent resistance properties, which are called “nonlinear resistance” because of the steeply curving graph presenting them in comparison with linear resistors. The device operates on the PTC (positive temperature coefficient) phenomenon. At room temperature, its resistance decreases with an increasing voltage until it reaches the breakdown point where the voltage creates an avalanche effect, causing a sharp rise in its resistance. This prevents the device from absorbing excessive energy and melting down in a power surge.

When the applied voltage exceeds the specified breakdown point, the current of the V575LC80CP is diverted from the protected electrical components to the ground, thus protecting them from the surge. When a surge surge ends, the device cools down, the resistance of it goes back to low again. The breakdown voltage of the V575LC80CP is typically lower than that of an MOV, making it better able to cope with fast-moving transients.

In summary, the V575LC80CP is a three-terminal, board-mounted, cylindrical metal-oxide varistor that is designed for use in power supplies and lightning-protecting applications. Its main application is in TVSSs, such as power strips, appliances, computers, and other electrical equipment, in order to provide protection from power surge events and spike voltages. Its working principle is based on its voltage-dependent resistance properties, which are called “nonlinear resistance” due to its sharp break-down point. This prevents the device from absorbing excessive energy and melting down when a surge occurs. The V575LC80CP offers optimal protection for sensitive electrical equipment against transients.
