TVS (Transient Voltage Suppressors) devices are widely used in the protection of electronic and power electronic components. Varistors, MOVs (Metal Oxide Varistor), Zener diodes, gas discharge tubes and other transient voltage suppressors are the common types of TVS components. These devices are used to limit the voltage that can flow through them in order to protect circuits from destructive over-voltage conditions. Among them, V20E35P application field and working principle stand out as the most popular and successful in various electronic systems.

The V20E35P is a ceramic-encased, non-polarized, bidirectional voltage-dependent resistors (VDRs) that is designed to function as an over-voltage protection device. It has a maximum breakdown over-voltage of 20 volts and a maximum peak current of 35A. The V20E35P is mechanically robust and possesses a wide operating temperature range from -55 ºC to 150 ºC. It is available in a compact package that ensures high level of performance even in small and confined spaces. The device offers excellent protection from over-voltages and over-currents, which makes it an ideal choice for inline circuit protection in a wide variety of applications. Some of the typical applications for which V20E35P can be used are high voltage/high current motors, generators, welding machines, compressors, high voltage terminals etc.

The working principle of V20E35P is based on the avalanche breakdown of the metal-oxide layers at its two interfaces. The metal-oxide layers are arranged in a serial-parallel configuration, forming a voltage-dependent resistance. When an over-voltage is applied across the V20E35P, the current through the device starts to increase exponentially due to the avalanche breakdown effect. This in turn increases the resistance of the device, which reduces the flow of the current and thus protects the components connected to it. The over-voltage protection provided by the V20E35P is instantaneous and non-destructive.

The V20E35P is a highly reliable and robust device that offers superior protection from over-voltages and over-currents. It has proven to be very successful in various high voltage/high current systems, and is constantly being improved and updated to keep up with the changing needs of the market. In addition to its superior performance, its small size and low cost make it an ideal choice for inline circuit protection in a wide variety of applications.
