TVS (Transient Voltage Suppressor) and MOV (Metal Oxide Varistor) components are electrical safety solutions found in many electronic products and applications. TVS and MOV products are designed to protect connected circuitry from damaging voltage spikes, lightning strikes, and current surges. B72210S0271K101 is one such type of TVS - Varistor

The B72210S0271K101 is a T-type, unidirectional varistor. It is designed for horizontal mounting on the printed circuit board in printed board applications. It is constructed of two electrode plates connected to an insulated substrate. The electrode plates are then covered with a metal oxide layer. The metal oxide layer can be adjusted to offer different protection levels and limiting voltages.

The primary application of the B72210S0271K101 is for ESD (Electro-Static Discharge) and surge protection. It can also be used for reverse field protection, overcharge protection, and clip on surge protection. Its protecting range is from 8V to 270V, with a breakdown voltage of 1500 V.

The working principle of the B72210S0271K101 is fairly simple. In the neutral state, the voltage across the varistor is minimal; however, when an electrical surge occurs, the voltage across the varistor increases, creating a current path, which in turn dissipates the surge, thus providing over-voltage protection.

When the overvoltage protection is activated, the circuit will break down, meaning that current will flow from the power supply to the ground. This is a useful protection feature as it ensures that the energy from the electrical surge or lightning strike is dissipated rather than harming the device or circuit.

The B72210S0271K101 can also provide over-current protection; this prevents the current from exceeding a safe level, which can damage the circuit and leads to possible destruction of the device. It does this by breaking down the circuit if the current is above the specified limit.

In summary, the B72210S0271K101 is an effective and reliable safety solution for power supplies and electronic circuits. It provides effective protection against damaging voltage spikes, lightning strikes, and current surges. Its working principle is simple; when an electrical surge occurs, the voltage across the varistor increases, creating a current path, which in turn dissipates the surge, thus providing electrical circuit protection.
