SMDJ180A is a high-power TVS diode designed to protect 180V DC rails against lightning-induced surges and inductive switching spikes. Featuring 3000W peak pulse capability (10/1000µs), it clamps transients quickly to reduce stress on MOSFETs, diodes and control circuitry. The DO-214AB (SMC) package supports compact, rugged layouts for industrial power and telecom equipment.
