TVS, or transient voltage suppressors (MOVs, or metal oxidative varistors), are essential components used when designing and developing electrical and electronic circuit boards. The B72220T2151K105 is a non-polarized varistor which is designed to offer protection against damaging voltage transients, for example, when an electrical surge or spike is detected.

The working principle of the B72220T2151K105 is based on the MOVs, which are metal oxide varistors made of several metal oxide layers that are connected in series. The voltage across each metal oxide layer determines its resistance and is called the varistor voltage. The varistor voltage is determined by the ratio of the metal oxide layers and their thickness, which vary depending on the purpose of their usage.

When a voltage transient occurs, the current flowing through the metal oxide layers will vary and increase until a certain point. This increase in current causes a breakdown between the metal oxide layers, thus increasing the resistance of the metal oxide layers and reducing the current, thereby suppressing the voltage transient.

B72220T2151K105 has a broad range of applications, especially in power supplies, automotive electronics, consumer electronics, and medical electronics. Its non-polarized characteristics make it ideal for a wide variety of uses, such as in power lines, where it provides protection against voltage overloads. In addition, it is also suitable for use in a number of other applications, including air conditioners, washing machines, microwave ovens, and light dimmers, to ensure protection against accidentally high voltage and current.

Due to its broad range of applications, the B72220T2151K105 can be used to protect a variety of components, such as high voltage capacitors, power supplies, power regulators, protection circuits, and other power electronics. As such, it is widely used in the electrical industry and can be found in many electronic devices.

In summary, the B72220T2151K105 is a non-polarized varistor which is designed to offer protection against damaging voltage transients, and has a wide range of applications. It works by using the MOVs which are metal oxide varistors made of several metal oxide layers connected in series, and when a voltage transient occurs, the current flowing through the layers increases until a certain point, which causes a breakdown between the layers. As such, the B72220T2151K105 is suitable for a variety of uses and can be found in many electronic devices, making it an essential component when it comes to designing and developing electrical and electronic circuit boards.
