SMDJ40A

SMDJ40A is a high-power TVS diode designed to protect 40V DC rails from lightning surges and inductive switching transients. With 3000W peak pulse capability and fast clamping response, it limits overvoltage stress on sensitive electronics. The DO-214AB (SMC) package enables rugged and space-efficient surge protection.
