TVS – Varistors, MOVs are a type of surge protection component used in the circuit to keep the voltage from over-stressing the insulation of the power input and the equipment connected to the power input. The protection components provide a temporary increase in resistance when the voltage rises above a predetermined threshold. The TVS-Varistors, MOVs provide a current carrying capacity in excess of the current rating of the equipment at that time.

VE07M00140K is one such device that provides excellent protection against transients due to lightning, static electricity, and other causes. It is a Bidirectional (Bi-direction) Silicon Avalanche Varistor (SiAV) and works by providing a low resistance path when the input voltage rises above the predetermined threshold. The low resistance path passes the current to the ground instead of through the circuit, thus preventing damage. The device is capable of peak 13A current and 6kA surge current.

The device also has a breakdown voltage of 140 V. This is the voltage at which the device begins to conduct current and provides protection against over-voltage. The working principle of the device is based on the principle of PN junction avalanche breakdown. The PN junction is a structure consisting of two types of doped material, P-type and N-type, placed in contact with each other. At low voltages, the majority carriers move easily from one side to the other, maintaining the balance. However, as the voltage increases, the carriers on one side of the junction start to drift faster towards the other side. This eventually leads to an avalanche effect, where more and more carriers are accelerated, rushing toward the other side of the junction.

The VE07M00140K is widely used in various applications including automotive, consumer electronics, medical & industrial, and telecommunications. In automotive applications, the device provides protection against transients caused by electrical faults and accidental contact with high voltage terminals, such as when repairing a car’s wiring. It is also used in consumer electronics to protect against voltage spikes and surges from power sources, which can damage sensitive circuit components. In medical and industrial applications, the device is widely used to protect the circuit from power surges during power outages, thus preventing damage to equipment. In telecommunications, the device is used to protect the telephone network from overvoltage damage, such as when lightning strikes.

In summary, the VE07M00140K is a bidirectional Silicon Avalanche Varistor, which provides a low resistance path to the ground when the input voltage rises above the threshold voltage. It is capable of handling peak 13A current and 6kA surge current and has a breakdown voltage of 140 V. The device is widely used in various applications such as automotive, consumer electronics, medical & industrial, and telecommunications to protect against transients due to electrical faults and voltage spikes/surges.
