Lightning protection is of critical importance for a variety of electrical and electronic systems, and among the various components used for this purpose, B72214S2211K101 has great performance in transient overvoltage protection. Classification is an important basis for understanding the composition of products, and B72214S2211K101 should be classified as TVS - Varistors, MOVs.

When there is a surge or common mode surge on the power or signal line, B72214S2211K101 will respond in a very short time (in nano second) and absorb and clamp transient overvoltage. After the overvoltage transient is absorbed, the conduction phase is instant and let the rest of overvoltage is dispelled gradually. The B72214S2211K101 is designed based on the multilayer varistor technology and the metal oxide elememt and is rated to hold the short-time 8/20µs wave peak or operating voltage up to 28V.

The main application area of B72214S2211K101 is the surge-protected electronic equipment. It is used in such products like data communication, automatic toll systems, LED display screens, televisions, electronic security systems, solar energy, motor drives, CNC systems, industrial automatic control systems, precision instruments, industrial control systems, VCD systems, and communication systems.

In terms of working principle and basic configuration, B72214S2211K101 is a varistor, also known as a voltage-dependent resistor (VDR). It is composed of a ceramic layer and what is known as a sintered multi-layer metal oxide semiconductor, which is made up of zinc oxide material. When no voltage is applied to the device, it acts like an open circuit, but when the applied AC or DC voltage is above its rated voltage level, the ceramic layer becomes active, and the resistance drops dramatically to allow electricity to flow in. The resistance of varistor decreases when the voltage increases, so it is also called negative resistance devices.

In summary, B72214S2211K101 is excellent in transient overvoltage protection and is classified as TVS - Varistors, MOVs. It is mainly used in surge-protected electronic equipment, such as data communication, LED display screens, electronic security systems, and so on. Its working principle is related to its basic configuration. Varistors are a type of voltage-dependent resistor and made up of ceramic layer and sintered multi-layer metal oxide semiconductor.
