V275LS4P Circuit Protection

TVS - Varistors, MOVs are broadly employed as surge protectors and voltage suppressors. The V275LS4P, specifically, is a varistor made up of low voltage, low volumetric, and low capacitance metal oxide semiconductor which can be used in the protection of integrated circuits, communication systems, cell phone designs, and other electronic assemblies operating in the low voltage range.

Varistors are devices made of a non-linear resistive element, and they tend to behave like a diode whose resistance varies according to the magnitude of the applied voltage. When the magnitude of this applied voltage exceeds the peak or clamping voltage of the device, the resistance offered by the varistor drops significantly, allowing it to act as a direct short-circuit to the applied voltage.

In the V275LS4P, the metal oxide element is housed in an axial leaded cylindrical package with a gray-colored surface. The device has a voltage rating of 275V and is designed to offer a maximum surge current handling capability of 20A. This device is manufactured with a specified noise level of 75V and a capacitance range of 140pF. The capacitance value determines the low frequency noise immunity of the V275LS4P, while its breakdown voltage defines the high frequency noise immunity.

The characteristic of the V275LS4P that sets it apart from other surge protectors in the same category is its clamping voltage. The device has an impressive clamping voltage of 229V, making it suitable for protecting circuits operating in a wide range of voltage levels. It is also designed to offer high transient energy absorption up to 400J, ensuring low power losses.

The V275LS4P is designed to offer superior circuit protection in telephone lines, communication lines, and consumer electronics. The device is also suitable for use in the automotive and computer markets, thanks to its ability to offer high surge current handling. A number of applications of the V275LS4P are listed below:
