TVS - Varistors, MOVs refers to a group of components that provide over-voltage protection for electronic circuits. The V120MT2B is an example of these devices and their application field and working principle is discussed in this article.

In general, the V120MT2B is used as a protection device in electronic circuits. It is designed to protect sensitive circuit components from over-voltage, over-current and other electrical hazards caused by electrostatic discharge (ESD). This component prevents damage to sensitive circuit components caused by voltage surges and capacitive currents. As such, it can be used in a variety of applications such as circuit boards, power supplies, telecommunications and computer systems.

The V120MT2B is a two-terminal device which consists of a semiconductor material and an integrated capacitor. It is designed to function as a varistor-type device, which is based on the principle of metal oxide varistor (MOV). This device operates on the principle of resistance variation when exposed to different levels of voltage. When voltage is placed through the device, the semiconductor material will be subjected to an electrostatic field which causes the resistance of the material to vary inversely with the applied voltage. This change in resistance provides protection against over-voltage conditions and is often referred to as ‘clamping’.

The V120MT2B also incorporates an integrated capacitor which helps to reduce the effects of high frequency voltage transients. This capacitor helps to limit the transient voltage excursion, thus improving the reliability of the device. The integrated capacitor also functions as a snubber which helps to absorb the high frequency energy and reduce the inrush current in the circuit.

In addition to the over-voltage protection provided by the V120MT2B, it also provides electrical insulation. This ensures that if the voltage of a nearby active component increases, the voltage of the protected device will remain the same. This makes the V120MT2B an ideal solution for protecting sensitive circuit components from voltage surges or capacitive currents.

The V120MT2B also offers a highly reliable and cost-effective method of protecting against electrostatic discharge. This device can be easily connected in series with the protected circuit, thus providing a low impedance path to ground. This ensures that any electrostatic voltage generated by the circuit will be quickly diverted away from the protected component.

In summary, the V120MT2B is a two-terminal device which provides over-voltage protection, electrical insulation and ESD protection. It is based on the principle of resistance variation and its integrated capacitor helps to reduce the effects of high frequency voltage transients. This makes the V120MT2B an ideal choice for a variety of applications such as circuit boards, power supplies, telecommunications and computer systems.
