B72207S170K401

B72207S170K401 application field and working principleTVS - Varistors, MOVs are used to protect circuits against electrical overstress such as voltage spikes and static charges. The B72207S170K401 is a two-terminal MOV, or Metal Oxide Varistor, that provides nonlinear response and superior surge withstand capability for protection against transient voltage transients.Working PrincipleThe working principle behind the B72207S170K401 is based on the nonlinear characteristics of a varistor. A varistor is essentially a semiconductor device that exhibits nonlinear voltage characteristics. When subjected to a voltage greater than its rated voltage, the varistor begins to conduct current. This is known as the “clamping” effect. In the case of the B72207S170K401, it is constructed using Zinc Oxide varistors and is designed with high-temperature and surge protection capabilities.The clamping voltage of the B72207S170K401 is 17 volts. Beyond this voltage, the varistor starts to conduct, allowing the excess surge to dissipate in the form of heat. The current that is dissipated is limited by the internal resistance of the device, meaning it is capable of handling large currents for short periods of time.Application FieldDue to its high-temperature and surge protection capabilities, the B72207S170K401 is often found in power supplies, satellite and telecom systems, and industrial and automotive systems. It can also be used to protect high-value circuit components from overvoltage transients.In power supplies, the B72207S170K401 is used to absorb energy from voltage spikes and surges produced by the power supply’s input. This prevents these voltage transients from propagating through the circuit and subsequently damaging the rest of the power supply’s components.In telecom systems, the B72207S170K401 is used to protect critical components from voltage transients caused by lightning strikes. The B72207S170K401 is also used to prevent overvoltage damage in industrial and automotive applications, where the device helps to prevent the initial voltage spike from propagating through the system.ConclusionThe B72207S170K401 is a two-terminal MOV that provides nonlinear response and superior surge withstand capability for protection against transient voltage transients. Due to the B72207S170K401’s ability to absorb energy from voltage spikes and surges, it is often found in power supplies, satellite and telecom systems, and industrial and automotive systems. It is also capable of protecting high-value components from overvoltage transients, making it an invaluable addition to any circuit design.
