The B72220S0421K101 is a SIOV metal oxide varistor from TDK Electronics, part of the StandarD series. It features a typical varistor voltage of 680V with a minimum of 612V and maximum of 748V. The device is rated for a maximum AC voltage of 420V and maximum DC voltage of 560V. It can handle a surge current of up to 8kA (8/20 µs waveform) and an energy absorption of 175J. The capacitance is 550pF at 1kHz.
The varistor is housed in a Disc 20mm package with radial tinned wire leads, designed for through hole mounting. The epoxy resin coating is flame-retardant to UL 94 V-0. Operating temperature range is -40°C to 105°C, with storage from -40°C to 125°C. Insulation resistance is at least 100MΩ and electric strength is at least 2.5kV RMS.
Typical applications include overvoltage protection in power supplies, industrial equipment, and consumer electronics where reliable transient suppression is required. The component is RoHS3 compliant and has an MSL of 1 (unlimited).
