The B72260B0681K001 is a type of transient voltage suppression (TVS) varistor. It is used for absorbing excessive high energy electrical pulses caused by transient voltage events. This type of varistor offers low profile and broad band protection against surge pulses. Additionally, the B72260B0681K001 provides excellent suppression of interference, shock, and vibration.

A varistor, sometimes referred to as a voltage-dependent resistor (VDR), is a nonlinear two-terminal electrical device. It is designed to provide an impedance path (between the two terminals) that varies with the applied voltage. The resistance of a varistor increases with decreasing voltage, making it suitable for dissipating energy from surges and spikes in AC or DC power lines. The B72260B0681K001 is a varistor that uses zinc oxide as the main active component in its electrical characteristics.

The B72260B0681K001 is mainly used for surge protection applications, such as protecting circuit components in automotive, telecommunications, and medical systems. It is used to dissipate energy from transient voltage events between the two terminals of a circuit, protecting from potential overvoltage damage. The B72260B0681K001 can also be used for electrostatic discharge (ESD) protection, such as protecting against ESD pulses in data and communication systems.

The working principle of the B72260B0681K001 is based on the Theory of Varistor Action of zinc oxide. When a voltage surge or spike (typically between -200V and +200V) is applied between the two terminals, it produces a stream of electrons and holes. These electrons and holes move across the zinc oxide grains and cause a rearrangement of the crystal lattice which reduces the electrical resistance of the device. As a result, the electromagnetic energy of the surge is slowly converted into thermal energy and dissipated safely.

The B72260B0681K001 is designed to provide low capacitance and broad-band protection against surge pulses. It is also designed to provide excellent protection performance over a wide range of temperatures, from -40°C to +85°C. Additionally, it is designed with a guaranteed leakage current of less than 2mA.

In summary, the B72260B0681K001 is a type of transient voltage suppression (TVS) varistor used for dissipating energy from transient voltage events between the two terminals of a circuit. It is mainly used for surge protection and electrostatic discharge (ESD) protection applications. It works based on the Theory of Varistor Action of zinc oxide and provides broad-band protection against surge pulses as well as excellent protection over a wide range of temperatures.
