The V420LS40CP is a Transient Voltage Suppression (TVS) device designed to protect sensitive components or equipment from voltage transients caused by electrostatic discharge, inductive load switching, and lightning. It is a member of the Varistor family, (also known as MOVs) which are used to guard delicate electronic circuits from destructive, high voltage spikes. The V420LS40CP is employed to protect motors, relays, cabling, circuit boards, and other exposed circuitry from potential damage due to industrial electrical noise.

The V420LS40CP is a nonlinear semiconductor device that has a unique threshold voltage characteristic. It is designed to suppress voltage transients above a given breakdown voltage. When an excessive voltage level is applied, a conduction current will flow from the anode of the device to the cathode of the device, thereby providing a parallel path for high voltage transient currents. This protects the elecctronic device from excessive voltage or current.

The V420LS40CP can be used in both AC and DC power circuits to protect against transients. When employed into an AC circuit, the device will conduct each time a transient voltage spike exceeds its threshold voltage. There is a limit on the amount of surge current the V420LS40CP can handle, so it should be used where the transients are typically within the rated surge current limit.

In a DC circuit, the V420LS40CP will protect the electronic equipment from trans
