The B72210S0681K101 is a commonly used TVS - Varistors, MOVs with a broad range of applications. It is a radial-leaded device with a rated leakage current of 1mA and a maximum clamping voltage of 36V. This device can protect electronic circuits from transients and increasing electricity voltage peaks. It also provides over-voltage and over-current protection capabilities.

The B72210S0681K101 is ideal for various video and audio applications. It is mainly used in audio/video equipment, computers, consumer electronics components, and telecommunications equipment. This device offers surge protection in applications with higher power supply lines such as high voltage power supplies, cellular phone base stations, telecommunications equipment, and communication lines.

In terms of its working principle, the B72210S0681K101 is a nonlinear resistive element that behaves differently under both AC and DC voltage scenarios. When exposed to AC voltage, it exhibits a large negative resistance. This allows the device to act as a voltage clamp, attenuating high-voltage transients. In DC situations, the device behaves more like a resistor and exhibits linear current-voltage characteristics.

The B72210S0681K101 is constructed with a ceramic base and a zinc oxide dielectric layer. A metal layer is deposited on the surface of the zinc oxide and forms an ohmic contact to the substrate. This layer serves as a back-up to the residual conductive layers of the zinc oxide dielectric. This device is able to withstand reverse voltages up to 10V, and is ideal for applications with supply voltages up to 36V.

The working principle of the B72210S0681K101 is based on the ability of the ZnO layer to withstand transient events by dissipating surge energies. As soon as the voltage level exceeds the breakdown voltage of the device, the ZnO layer is activated to conduct the current and dissipate the energy. The device is able to absorb large surge currents of up to 250A.

The B72210S0681K101 is an easy-to-use and reliable TVS - Varistors, MOVs. It is well suited for applications requiring over-voltage and over-current protection. Its simple design and robust construction make it an ideal solution for many audio/video, consumer electronics, computer and telecom applications.
