The TDK B72210S0250K101 is a metal oxide varistor (MOV) from the SIOV StandarD series, designed for overvoltage protection in electronic circuits. It features a typical varistor voltage of 39V, with a minimum of 35.1V and maximum of 42.9V, and can handle a maximum AC voltage of 25V and DC voltage of 31V.
This varistor offers a surge current rating of 500A for a single 8/20 µs pulse and 250A for 15 repeated pulses, with an energy rating of 3.7J at 2ms. It dissipates up to 0.05W and has a typical capacitance of 3200pF at 1kHz, making it suitable for transient suppression in low-voltage applications.
The component is housed in a Disc 10mm package with through-hole mounting, suitable for PCB assembly. It operates over a temperature range of -40°C to 105°C and meets the climatic category 40/105/56 per IEC 60068-1, with electric strength of at least 2.5kVRMS and insulation resistance of at least 100MΩ.
Typical applications include surge protection in power supplies, industrial controls, and consumer electronics where protection against voltage transients is required. The epoxy resin coating is flame-retardant to UL 94 V-0, and terminals are tinned wire for reliable soldering.
