Product details

1500 W peak pulse — what it means on the board

The 1.5SMC51A-M3/57T: Single unidirectional channel — one diode per package, cathode band marked on the DO-214AB body, polarity matters when you place it across the rail.

DO-214AB (SMC) surface-mount package, also known as SMCJ — standard footprint, no special pad geometry beyond the datasheet land pattern. Supplied on Tape & Reel — pick-and-place ready; no moisture sensitivity level stated in this record, so assume standard MSL per the Vishay series datasheet.
