TVS – Varistors, MOVs and B72241L0251K100 Application Field and Working Principle

TVS or transient voltage suppressors are components that are designed to protect vulnerable electronics from high-voltage surges. They are commonly found in power supplies and computer circuits. The most common type of TVS is the varistor, also known as a voltage-dependent resistor (VDR). Varistors limit the voltage to a predetermined level by providing a low-resistance path when a certain voltage is reached.MOVs or metal-oxide varistors are another type of transient voltage suppressors that provide greater protection against high-voltage surges than varistors. MOVs limit the surge current to a predetermined level by providing a low-impedance path when a pre-defined voltage is reached. MOVs are typically used to protect sensitive electronic components from high-voltage transients.In this article, we’ll take a closer look at the B72241L0251K100 and its application field and working principle.The B72241L0251K100 is an MOV designed to protect electric and electronic equipment from transient voltage surges. It is designed to provide protection against lightning strikes and disturbances in the power grid. The B72241L0251K100 is ideal for use in power supplies, computers, telecom circuits, and other high-voltage applications.The B72241L0251K100 is a non-polarized, three-terminal device with a rectangular metal oxide varistor element connected in series with a high-current gas discharge tube. The varistor element is constructed of semiconductor material with a zener diode-like electrical characteristic. The gas discharge tube is filled with an inert gas and two electrodes to provide a low-impedance path when the breakdown voltage is reached.In normal operation, the B72241L0251K100 provides a high impedance path, which allows current to pass through the circuit. When a surge voltage is applied, the varistor element begins to conduct and clamps the voltage to its defined breakdown voltage, thereby preventing the surge voltage from damaging the protected circuit.The B72241L0251K100 is designed to work in the range of 200V to 600V and provides a continuous failure rate of 5%, which means that it is quite reliable. It also has a high surge current rating of 80A which ensures that it can handle even large surges without failing.In summary, the B72241L0251K100 is designed to protect electric and electronic equipment from transient voltage surges. It is designed to provide protection against lightning strikes and disturbances in the power grid. The MOV is non-polarized, three-terminal device with a rectangular metal oxide varistor element connected in series with a high-current gas discharge tube. This TVS is designed to work in the range of 200V to 600V and provides a continuous failure rate of 5% and a high surge current rating of 80A.
