TVS (transient voltage suppressors) and MOVs (metal oxide varistors) are two common types of Varistors used in a variety of applications. MOVs have a variable resistance that can be used to protect against over and undervoltage conditions, while TVS devices are used for surge protection. The V420LT40CP is a varistor designed for high-temperature applications and provides surge protection for electronic equipment. This article will provide an overview of this varistor and its application field and working principle.

The V420LT40CP is a fast-responding, nonsymmetrical discrete varistor designed for high temperature applications. The device has a reverse standoff voltage of 420V with a maximum repetitive peak off-state voltage of 1.2kV. It can handle up to 34 Amps of surge current and offers a wide range of response times, ranging from 2.25 to 39.7 μsec. The device has a maximum operating temperature of 125°C, making it well suited for demanding applications. Additionally, the V420LT40CP is hermetically sealed for dust, moisture and heat protection.

The V420LT40CP can be used in various applications such as consumer and automotive electronics, lighting systems, telecom infrastructure equipment, industrial equipment, and more. It provides effective overvoltage protection for applications such as AC power line protection and lightning protection. The device can also be used in railway systems, data centers, and industrial or medical equipment.

The working principle of the V420LT40CP is fairly straightforward. When an inrush of current is detected, the device will divert the current away from the device and prevents the overvoltage from exceeding the “clamping” voltage of the varistor. The “clamping” voltage of the device is determined by the reverse standoff voltage of the device, which is 420V in the case of the V420LT40CP. After diverting the current, the device will redirect the current to the ground, thus preventing any damage to the components and circuits.

In summary, the V420LT40CP is a type of fast-responding, nonsymmetrical varistor designed for applications requiring high temperature and surge protection. The device is hermetically sealed and has a reverse standoff voltage of 420V with a maximum repetitive peak off-state voltage of 1.2kV. It is well suited for applications such as consumer and automotive electronics, telecom infrastructure equipment, railway systems, and industrial or medical equipment. The working principle of the device is to divert the inrush of current away from the device and redirects the current to the ground.
