The V660LU80CPX10 is a general-purpose AC transbiasing varistor designed for system noise protection. It provides superior unidirectional suppression for fast transients. This is a popular varistor in multiple systems, and it is used to help protect sensitive electronics from AC transients. Its working principle, application areas, and specifications are discussed in this article.

How Does the V660LU80CPX10 Work?

The Varistor V660LU80CPX10 is a varistor, an electronic device used to provide protection for sensitive circuits from AC voltage transients. It works by sensing the incoming AC voltage and responding to it with a rapid voltage adjustment. This helps protect the system from dangerous voltage surges that can damage the circuit.

The V660LU80CPX10 can be considered to be a combined protective device. It contains two elements that work together to protect the circuit from AC transients. The design relies on a metal-oxide varistor (MOV) element to sense and suppress overvoltage transients, and it also contains a thermally sensitive, reverse biased diode.

The MOV element of the V660LU80CPX10 works as a voltage-dependent resistor. It does this by monitoring the incoming AC signal, and when an overvoltage is detected, it responds by quickly connecting high resistance between the input and output terminals. This helps to reduce the surge voltage across the protected circuit.

The diode element of the V660LU80CPX10 is used to protect against reverse-current transients. When a reverse-current transient is detected, the diode triggers a low impedance path to ground and shunts the current away from the protected circuit.
