The SMCJ45E3/TR13 is a unidirectional Zener TVS diode rated for 1500W peak pulse power (10/1000µs waveform) with a reverse standoff voltage of 45V. The clamping voltage at peak pulse current (18.7A) is 80.3V max, which defines the voltage spike the downstream circuitry must survive.
Microchip lists the SMCJ45E3/TR13 as Active. There is no PCN or EOL notice on this base product number. Supplied in tape & reel (TR suffix) for automated pick-and-place.
Package and mounting — DO-214AB (SMC) footprint
Surface-mount DO-214AB (SMCJ) package, unidirectional channel. The cathode band identifies the anode-to-ground orientation.
