TVS - Varistors, MOVsA varistor is a voltage tunable non-linear. It is a two-terminal semiconductor element and one of the most essential electronic components. Varistors or metal oxide varistors (MOVs) are two terminal electronic components that protect circuits from electrical overvoltage conditions. B72530T1250K62 is one of the Varistor models available and is widely used in many application fields for circuit protection and clamping.The working principle of the B72530T1250K62 is based on the semiconductor junction. When the applied voltage is below the breakdown voltage of the diode, the current is very low. However when the applied voltage is above the breakdown voltage, the current suddenly increases due to the avalanche effect caused by the electric field of the junction. This is the principle on which varistors work.The B72530T1250K62 Varistor is designed for applications in AC and DC circuit protection. It is designed for use in electrical power supplies, communications, consumer electronics and automotive electronics. It is used to provide surge protection from overvoltage caused by lightning strikes, power surges and electrostatic discharge.The main features of the B72530T1250K62 include high voltage break down, surge current peak pulse power dissipation of 1500W and capacitance of 1250pF. It also has very low leakage current and features a high temperature rating of 175°C.
