Transverse electric field (TMOV20R460M) is commonly used for voltage spike protection in electronics. This device is an overvoltage protection device with surge current capability, it supports both transverse and longitudinal electric fields. It provides efficient protection against electrostatic discharge (ESD) and electrical overstress (EOS).

Varistors, also known as MOVs, are a form of a voltage-dependent resistor, which are used as a form of protection against overvoltage. Transverse electric field, MOV is a type of varistor, designed to absorb voltage spikes. It has the advantages of high insulation resistance, low leakage current, low capacitive reactance and surge current capability. Unlike the traditional Varistors, the MOVs can withstand several thousand volts and are able to absorb higher surge currents because of their complicated multi-layer structure.

TMOV20R460M is one such MOV, designed for applications requiring high discharge current capability. This MOV has an operating temperature range of -55 degrees Celsius to +85 degrees Celsius and its maximum working voltage is 450Vac. It is also UL approved and has low leakage current ratings, making it an ideal choice for overvoltage protection in any environment. The MOV can handle high surge current and protect the electronics or equipment from overvoltage events, such as lighting or electrostatic discharge.

In terms of working principle, a MOV consists of a number of small plates of metal sandwiched together, which create several bridge junctions. When an overvoltage is applied to the MOV, electrons collect at the junctions and create a conductive path. This creates a resistive path which absorbs the voltage, effectively limiting the electrostatic discharge or overvoltage. The resistance of the MOV changes with the applied voltage, thus providing protection up to its specified voltage rating.

In conclusion, TMOV20R460M is a highly efficient voltage spike protection device suitable for protection against overvoltage caused by electrical overstress or electrostatic discharge and operate within its temperature range. This MOV will provide efficient protection for the electronic system from potential damage caused by overvoltage. TMOV20R460M is a form of Varistor and works according to its working principle of bridge junctions, limiting the voltage of any overvoltage and thus providing reliable protection.
