SMDJ220CA is a high-power bidirectional TVS diode designed to protect 220V AC/DC lines and high-voltage interfaces from destructive transients. Rated at 3000W peak pulse power (10/1000µs), it delivers fast, symmetrical clamping for both polarities of surge events. The DO-214AB (SMC) package supports rugged designs in industrial controls, telecom equipment and high-voltage power protection.
