TVS - Varistors, MOVs A TVS (transient voltage suppression) device is a form of voltage-controlled resistor designed to suppress transients caused by electrostatic discharge (ESD), lightning, or other voltage surges. A TVS device will reduce the voltage that spikes to a safe level and protect other components and circuits. TVS protection devices include varistors (VDRs), diodes, and metal oxide varistors (MOVs). B72520T1140S272 is an example of an MOV device.MOVs are also known as varistors and are composed of zinc oxide and other materials in a disk shape. Depending on the device, they can be designed for a relatively broad range of pulse wave forms. MOVs protect electrical and electronic equipment from over voltages, power surges, and transients. MOVs respond quickly to a voltage surge by providing a low impedance path that limits the voltage rise above the surge threshold. As the voltage returns to normal levels, the resistance of the MOV will increase again. MOVs are often used as AC line protection in computers and home-entertainment systems, and also provide ESD and transient suppression in automotive systems. The B72520T1140S272 is an automotive-grade TMOV device with low maximum let-through voltage (MLTV) levels. It provides an ESD rating of 30KV HBM and a surge current capability of 40A (8/20us). This MOV is also conformal coated for extra protection against environmental hazards and has built-in heat dissipation for thermal stability. The working principle of the B72520T1140S272 is simple. It functions by allowing current to flow between two electrodes when the voltage exceeds a certain threshold level. The resistance of the device increases when the voltage returns to normal levels, and it dissipates the energy that would otherwise have gone to the connected circuitry.The B72520T1140S272 is suitable for a variety of applications requiring superior protection against over voltage and surges, including automotive systems, consumer electronics, and telecommunications. It can be used as an AC line protector and is ideal for protecting against short-term, high-energy transients in battery systems. It can also be used to protect primary switching devices and as an ESD protection device for automotive systems.In summary, the B72520T1140S272 is a robust MOV device designed to protect a wide range of automotive, consumer electronics, and telecommunications applications from over voltage and surges. It features low MLTV levels, conformal coating, and built-in heat dissipation for superior protection. The device works by providing a low impedance path when the voltage exceeds a certain threshold level, dissipating the energy that would otherwise have gone to the connected circuitry.
