TVS - Varistors, MOVs are commonly used in a variety of applications to provide an overvoltage protection mechanism and reduce switching noise.

V420LU7P is a unidirectional Transient Voltage Suppressor TVS Diode designed to protect sensitive electronic equipment from destructive electrical transients. The device is optimized for application in High Temperature, High Reliability and Low Capacitance products. It provides dual series surge protection which, when combined with series resistors, can handle multiple surge conditions with fast recovery time.

The V420LU7P has excellent clamping characteristics for transient voltage, dV/dt, and dI/dt. It also provides excellent noise immunity characteristics for high-speed circuit designs. This device is designed to meet or exceed the requirements of Low Capacitance TVS’s such as IEC 61000-4-5, IEC 61000-4-2, EN 61000-4-2, EN 61000-4-5 and other standards. The V420LU7P is constructed from resilient rubber and offers low capacitance and power consumption levels.

This TVS device is ideally suited for use in both consumer and industrial electronic equipment. Typical applications include protection for data lines such as USB, Ethernet, IEEE 1394, RS-232, RS-485, etc. It can also be used in telecommunications, medical, automotive electronics, motors, and various other applications.

The working principle of the V420LU7P device involves a combination of a metal oxide varistor (MOV) and a diode. The MOV is the core component that provides the main surge protection. When a transient surge is applied, the MOV conducts the surge current and absorbs the energy of the surge. The reactance of the diode then clamps any residual transient voltage.

The V420LU7P device is designed to provide robust protection against overvoltage transients such as ESD, EFT, and surge events. The device can be used in a multitude of applications, including protection of data lines, telecommunications equipment, and automotive electronics. This device is designed to provide fast response times and low capacitance levels.
