TVS - Varistors, MOVs, are used in a wide variety of applications to protect circuits from surge voltages and decrease electric current in the event of an overload. The V275LT40CP Varistor is an ideal solution for engineers looking to incorporate robust surge protection in their designs. This product features an industry-standard form factor with UL 94V-0 thermoplastic casing to withstand the harshest environmental conditions.

The V275LT40CP is part of the family of varistors manufactured by Vishay Intertechnology. This product has a VDC rating of 275 Volts, marking it suitable for use in a variety of applications including communications, automotive, and industrial control designs. Standard Low Temp Coefficient (LT) versions are available with Maximum Allowable Working Voltage of ≤ 250V and Clamping Voltage of ≤300V.

A varistor is basically a two-terminal solid-state component that has a non-linear voltage-current characteristic. It is incredibly important in preventing damage done to a circuit in the event of an overload or surge voltage, as it rapidly diverts large current from a circuit and away from sensitive equipment. The V275LT40CP is designed to clamp the voltage between its terminals to a predetermined maximum value regardless of the applied surge or spike duration. In the event of a voltage increase, the varistor will switch its electrical properties, maintaining this clamping voltage until the voltage returns to normal.

The V275LT40CP Varistor is manufactured with Vishay’s patented High-Charge Protection Technology™ which offers superior surge protection performance compared to conventional varistors. This technology automates the recovery process of the varistor, accelerating the resetting of the device to help reduce downtime and ensure reliable performance. Combined with its high thermal stability and durability this solution ensures consistent performance levels regardless of the environmental conditions, allowing it to operate in temperatures between -55°C and 125°C.

The V275LT40CP Varistor also benefits from built-in thermal and electrical overload protection. This ensures that the device can withstand extremely high currents before reaching its maximum allowable temperature. This makes it suitable for a wide range of applications where power is subject to fluctuation, and harsh environmental conditions.

The V275LT40CP Varistor is a highly reliable device that is available in a range of different package sizes. It is ideal for use in a variety of fields, such as communications, automotive, and industrial control designs. Applications include overvoltage protection, overcurrent protection, AC overvoltage protection, EMC suppression, and lightning protection.
