TVS (transient voltage suppression) technology is one of the more widely used means for providing reliable protection from over-voltage transients. The device contains a special structure, usually a ceramic disc with a large anode electrode, having an electrode connected to it.

The V420SM7 is one of the best known and most popular TVS devices. Developed for both commercial and industrial applications, the V420SM7 is a varistor-type TVS component that is designed to detect and then quickly suppress transients up to 420V.

The V420SM7 can be used in many different applications including automotive, consumer electronics, industrial equipment, telecommunications, and LED lighting. It is suitable for applications that require a fast response time and a maximum transience peak pulse power of 510W.

The V420SM7 works by quickly shunting the excess current away from the sensitive components when there is an over-voltage transient. The active element in the device is a metal oxide varistor (MOV) which is a special type of diode that is designed to detect and then quickly dissipate energy from high-voltage transients.

When an over-voltage transient is detected, the MOV will quickly act as a power clamp, reducing the voltage that is applied to the protected elements. This allows the equipment to safely operate without damage. The MOV is usually configured to handle a specified peak pulse power rating.

The V420SM7 is a low-profile device which uses a small footprint to provide reliable protection from over-voltage transients. It is also rated for a wide range of temperature ratings, from -55°C to 85°C and can be used in environments with high-temperature extreme temperatures.

The V420SM7 is a reliable and high-performance device that is designed to protect sensitive components from damaging over-voltage transients. It is suitable for a wide range of applications including automotive, consumer electronics, industrial equipment, telecommunications, and LED lighting.
