A TVS, Multi-layer varistor (MOV) or Metal Oxide Varistor (MOV) is an electrical component used to protect electronics from sudden abnormal voltages, particularly in the form of static electricity and electrical transients also known as ‘spikes’. The V10E300PL3B7 is aHigh Energy Varistor (HEV) developed to protect USB 3.0 ports and provide safe voltage clamping across the DC-IN and USB, as well as ESD protection for USB 2.0 ports. The V10E300PL3B7 has the ability to tolerate large surge currents up to 4 kA (8/20 μs) per IEC 61000-4-5.

The V10E300PL3B7 has a multilayer varistor structure consisting of discs of two different materials; a Ceramic Dielectric layer and zincoxide discs. The Ceramic dielectric layer in between the zincoxide discs works like an insulator. When the device is subjected to a voltage spike, the ceramic layers break down enough to create a conducting path between the zinc discs in order to divert the excess energy away from the device.

The working principle of the V10E300PL3B7 is based on the characteristics of the multilayer varistor (MOV) structure. As the voltage increases, a greater number of electrons can pass through the ceramic dielectric layers from one zinc oxide disc to the next. This forms a conducting path that diverts the excess current away from the device. The conducting path is broken down once the surge current is dissipated, the voltage drops and the ceramic layers are no longer subjected to stress.

The V10E300PL3B7 is designed for use in applications such as USB 3.0 ports, PD controllers, and devices subject to large inrush currents. It can be used in applications where the overvoltage protection requirements are up to 10A, with a working current range of 300VAC to 3,700A. It provides surge protection, overvoltage protection, and ESD protection to prolong the lifespan of 24/7 operating electronics.

The V10E300PL3B7 is ideal for applications that require high surge current protection, such as USB 3.0 ports, PD controllers and other sensitive electronics. It provides overvoltage protection and ESD protection up to 3,700VAC and 4kA, preventing the device from being damaged by sudden voltage spikes. The V10E300PL3B7 is an ideal choice for applications where 24/7 operation is required, providing the highest level of protection for sensitive electronics.
