The TDK B72220S2271K101 is a metal oxide varistor (MOV) from the SIOV AdvanceD series, designed for overvoltage protection in AC and DC applications. It features a typical varistor voltage of 430V (range 387V to 473V) and is rated for a maximum AC voltage of 275V and maximum DC voltage of 350V. The device can handle surge currents up to 10kA (8/20 µs waveform, single pulse) and has a nominal surge current rating of 3kA (8/20 µs, 15 pulses).
With an energy rating of 215J (2 ms pulse) and typical capacitance of 850pF at 1kHz, this varistor provides robust transient energy absorption. The component is housed in a 20mm disc package with radial tinned wire leads for through-hole mounting. The epoxy resin coating is flame-retardant to UL 94 V-0, and the device operates over a temperature range of -40°C to +105°C.
This varistor is suitable for protecting power supplies, industrial equipment, and consumer electronics from voltage transients and surges. Its high surge current capability and energy absorption make it appropriate for applications requiring reliable overvoltage clamping. The through-hole package allows for easy manual or automated assembly in PCB designs.
