The B72220U2271K501 is a metal oxide varistor (MOV) from TDK Corporation's SNF AdvanceD series. It features a typical varistor voltage of 430V (387V min, 473V max at 1mA DC) and can handle maximum AC voltages of 275V and maximum DC voltages of 350V. The device is rated for a maximum surge current of 10kA (8/20µs single pulse) and an energy absorption of 215J (2ms). Capacitance is 850pF typical at 1kHz.
This varistor is designed for high-energy surge protection in harsh environments. It operates over a temperature range of -40°C to +125°C and is housed in a 20mm disc package with through-hole mounting. The coating is silicon resin, flame retardant to UL 94 V-0, and terminals are tinned wire. Delivery is in bulk.
Typical applications include AC line surge protection, DC power supply circuits, and industrial equipment protection against transient overvoltages. The part is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited).
