Transient voltage suppressors, or TVS for short, are designed to help protect components from electrical overvoltages. They come in many different shapes and sizes.The B72587E3140S218 is a kind of varistor, which is a type of TVS. It is a multilayer varistor, usually used in off-board or remote applications.

The B72587E3140S 218 is a non-poled, non-ergodic, non-directional device. It is made up of a stack of MOV disc elements, which are connected in series with each other.The discs are made from a special material which has high electrical insulation properties, meaning it can withstand large voltages when in a quiescent state. This material also has a high current carrying capacity, allowing it to withstand higher current surges even when there are large voltage spikes. The discs also have an oxide layer, which helps to reduce any arcing or sparking caused by the high voltage.

The B72587E3140S218 is typically used in the more sensitive parts of a circuit, such as the power supply, signal conditioning, or control circuitry. It is also used for battery protection and circuit protection, where large voltage or current surges can damage components. As it has a very high current carrying capacity and a low clamping voltage, it is particularly suitable for applications where large voltage spikes are expected.

The working principle of the B72587E3140S218 is that it “clamps” the excess voltage from the power source, thus preventing the overvoltage from reaching other components in the circuit and damaging them. This is done through its high dielectric strength and resistance to arcing. When the voltage exceeds the varistor’s clamping voltage, the MOV discs open up and block the high voltage from entering the circuit. The MOV discs then close again when the voltage returns to normal levels.

In summary, the B72587E3140S218 is a type of varistor, or transient voltage suppressor, designed to help protect components from electrical overvoltages. It is composed of multiple MOV discs, which open up and block high voltage spikes from entering a circuit. Its high dielectric strength and resistance to arcing make it ideal for applications which require high current carrying capacity and low clamping voltage. The B72587E3140S218 is typically used in power supplies, signal conditioning, control circuitry, and for battery protection and circuit protection.
