Transient voltage suppression devices (TVS) are components that provide robustness against transient voltage surge. Varistors, MOVs (metal oxide varistors), and diodes are the three main types of transient voltage suppression (TVS) devices. Among these three varieties, the B72220T2321K105 is considered as a ‘metal oxide varistor’, or MOV, which serves as the most widely used type of transient voltage suppression device. This type of component is designed to accept and safely dissipate high voltage surges and also protect the voltage sensitive components within a circuit from potentially dangerous electrical sparks caused by static, lightning, and other sources of electrostatic discharge.

The B72220T2321K105 metal oxide varistor is an especially advanced device that offers reliable protection for sensitive electronic components in applications such as automotive, consumer electronics, electrical and industrial equipment, and power systems. This MOV is especially designed to effectively protect circuits in applications where AC line to ground fault transient surge protection is required. The device also boasts an ideal resistance-capacitance (RC) time constant, which assures fast transient suppression due to its superior capacitance stability over voltage and temperature ranges.

The B72220T2321K105 metal oxide varistor component is composed of a number of cylindrical discs made of sintered zinc oxide grains. All these grains are embedded in a special epoxy resin casing. These discs are connected in a series and interconnections are made by tin clips. The MOV can withstand high surge voltage in the order of 2000 volts. The number of discs in the device varies according to the desired surge rating. The bigger the number of discs, the higher the surge rating of the MOV is.

In terms of its working principle, when the MOV is subjected to a surge voltage, electrons in the zinc oxide grains of the component move and populate the higher energy states. This results in an increase in temperature which causes the electrons to return to their original positions and releases the surge. Voltage is regulated in this process and the component dissipates the surge energy over a short period of time. This prevents any destruction of the protected circuit from the surge voltage.

In summary, the B72220T2321K105 metal oxide varistor is an exceptionally reliable and robust transient protection device that can be used in a variety of industries and applications. Its fast response time, superior capacitance stability over different voltage and temperature ranges, and high surge rating makes it a flexible and practical solution for surge suppression.
