TVS - Varistors, MOVs

B72220S2511K101 application field and working principle, In the electrical world, TVS - Varistors, MOVs are very common. It stands for Transient Voltage Suppressors, which are basically overvoltage protection devices. Hardly anyone knows it as it\'s simply known by its initials. It is, however, a very convenient and safe way to protect sensitive electrical components from potential damage due to unexpected power surges, electrical transients or extreme voltage levels.

Travelling waves in some mains power supplies can exceed the supply voltage. These abrupt increases in voltage finally reach the output of the supply, arriving at the load. To protect the load from voltage spikes, there’s a need for overvoltage protection.

The B72220S2511K101 is a TVS used as a path to ground for such overvoltage. It has a variety of uses in small, medium and large-scale applications. The B72220S2511K101 is normally available with a maximum peak pulse power rating of 25W and reverse breakover voltage of 11v.

The B72220S2511K101 is a two-terminal device designed to protect sensitive electronic components from damage due to high voltage, electrical transients or short circuits. The device is a bi-directional TVS diode, clamping the voltage to a set clamping. Its characteristic helps in reducing EMI / ESD. The B72220S2511K101 has a maximum working voltage of 11v, breaking down at a specified voltage.

Apart from protecting against power surges, a TVS is also very effective in protecting sensitive data line signals, such as RS-232 and RS-422 protocols. It can also be used to protect isolated switching circuits, grounding circuits and power supply circuits. The B72220S2511K101 can also be used as an ESD (Electro-Static Discharge) Protection Device. It can also be used as a voltage regulator in the automotive field.

The working principle of B72220S2511K101 is simple and efficient. It has two terminals, one for the line side and another for the load side. The device works by conducting current during reversal of the applied voltage across the terminals, and blocking current when the voltage is less than the specified breakdown voltage. When the applied voltage exceeds its clamping voltage, the TVS diode acts as a short-circuit to ground, allowing the voltage to discharge safely.

In summary, the B72220S2511K101 is a very versatile device, suitable for protection against high voltage in any application, from industrial and military applications to consumer electronics. Its low-cost design and wide range of uses make it an attractive option for most businesses.
