TVS - Varistors, MOVs

Transient Voltage Surge Suppressors (TVS) are devices that protect sensitive electronics from overvoltage transients in electrical lines. Varistors, also known as Metal Oxide Varistors (MOVs) are one type of TVS. MOVs provide protection from voltage transients, either from electrical noise or from current surge. They are made from a composite of semiconductors and metal oxides in order to withstand the high transient voltages. Among the most popular type of MOVs is the infamous TMOV20RP300M. This device offers great protection for a range of applications from different types of overvoltages.

The TMOV20RP300M is a 20mm radial component designed for use in overvoltage protection circuits and offers up to 300V transient overvoltage protection. It is built with a ceramic body and is capable of providing protection from transient overvoltages up to 2000V. Its radial design allows it to be used in space constrained applications, while its simple, plug and play installation provides convenience in its use. The MOV also prevents overvoltage transients from entering the system with its high peak peak pulse power capability of up to 8kW.

The TMOV20RP300M has a broad range of application fields due to its versatile design and built in protector features. The MOV is very popular in the personal computer industry for protecting motherboards from electrical surges due to its 20mm radial design. It is also widely used in telecommunications equipment such as modems, routers and switches in order to protect against impulse voltage caused by lightning strikes and power surges. Additionally, industrial applications such as AC/DC converters, and motor drives, have used the TMOV20RP300M in order to protect their sensitive equipment from overvoltage transients.

The TMOV20RP300M has a simple working principle which is based on its voltage clamping mechanism. In its basic function, the device acts like an electrical shunt which diverts any overvoltages to ground. This is done by the device limiting the voltage of an overvoltage transient to a safe level, and a continued reduction of any subsequent peaks of the same transient. In the event of a surge, the device has a low capacitance breakdown which will absorb any excess current, forming a high impedance path and allowing for controlled breakdown. This process enables the device to remain operational even under prolonged high voltage conditions.

The TMOV20RP300M offers great protection and is designed with convenience and safety in mind. Its 20mm radial design enables space constrained applications, while its simple plug and play installation makes for a straightforward installation process. Its working principle ensures that the device can provide overvoltage protection against electrical surges as well as impulse voltages caused by lightning strikes. This makes the TMOV20RP300M an ideal device for a broad range of applications from personal computers to industrial machines.
