TMOV20RP115M is one of the most used series of varistor/metal oxide varistor and metal oxide surge arrester. It has a 2 pole (2P) surge arrester with a very wide range of voltage from 7V to 1800V, while its maximum rated current reaches up to 65A. It is applied to protect devices such as rectifier outputs, circuit boards, and switching power supplies. It is typically used for installation in power systems, electronic equipment, and machine tools.

The working principle of TMOV20RP115M is based on the dynamic clamping action of the metal oxide varistor, where when the voltage across its terminals increases beyond the threshold voltage, the quantum size effect of the varistor will cause the electrons to tunnel from the valence band to the conduction band, forming a conducting path through the varistor material. The varistor then acts as an electronic shock absorber and will draw current up to its maximum allowed current. This will, in turn, dissipate energy from the surge and protect the device being shored up.

The featured design of TMOV20RP115M also has an improved clamping voltage coefficient (CVC) that brings an extended voltage range to the protection. This guarantees a superior performance to the MOVs that are the same or similar to voltage range. The temperature coefficient of TMOV20RP115M also features total thermal stability over wide temperature variation, allowing the device unmatched stability and performance.

This series of surge arrester has proven itself to be the ideal cost-saving solution to the problems posed by overvoltage and transients, and has been used in several situations including but not limited to office equipment, consumer appliances, industrial equipment, LED lighting, home automation, and HVAC systems. Not only this, but it is also certified by UL 1449, CSA, VDE, CE, FCC, and RoHS.

In conclusion, TMOV20RP115M is an advanced solution to surge protection, designed to provide superior protection and long-term stability against overvoltage and transients. Its wide voltage range and temperature coefficient also add to its functionality and usability, making it an ideal choice for a wide range of applications involved with protecting electrical devices from surge-induced damage.
