TVS (Transient Voltage Suppressor) devices such as Varistors, MOVs (Metal Oxide Varistors) are common in the market today for protection of a wide variety of electrical and electronic circuits. In this article, we will focus on the application field and working principle of the TMOV20R130M device.

The TMOV20R130M is a MOV type of Transient Voltage Suppressor. It offers high surge current protection and dissipates much less power than a normal MOV. It has a clamping voltage of 135V (2.0xUnom), a peak lead current of 350A (8/20μs) and a nominal surge current of 10kA (8/20μs, 10 times/2) and provides excellent surge protection for a wide variety of electrical and electronic circuits that are exposed to surges. It is also designed to self-protect itself from damage and to minimize power dissipation during normal conditions.

The TMOV20R130M is mainly used to protect electronic circuits from hazardous overvoltage events, such as those caused by lightning and electrostatic discharge. It can be installed in AC power supply systems, telecommunication systems, and DC power supplies to protect circuits within these systems from both transient overvoltage and current. In addition, the device can be used in power line side surge protection, data line surge protection, ESD/ESP protection, automotive electronics, consumer electronics, and power electronics.

The working principle of the TMOV20R130M is relatively simple. When exposed to a surge or overvoltage event, the device will act as a dynamic voltage clamping device and protect whatever circuit it is connected to by diverting the flow of energy away and dissipating it safely. This phenomenon occurs due to the kinetic energy of the electrons within the material, as electrons move up and down between the electrodes when subjected to an electric field. The device also features an autoreset capability which prevents it from being damaged by putting it into a low impedance state after the surge event has passed.

In conclusion, the TMOV20R130M is a useful device for protecting electronic circuits from hazardous overvoltage events. The device not only provides basic protective characteristics, but can also feature a reset capability to reduce the burden of manual resetting after surge events. And with its wide range of application fields and its simple working principle, it is an effective and affordable solution for protecting electronic circuits.
