1500 W surge clamp in a DO-214AB footprint
The 1.5SMC120A-E3/9AT: It clamps a 102 V reverse standoff rail at 165 V maximum, shunting up to 9.1 A of surge current. The DO-214AB (SMCJ) surface-mount package fits standard reflow profiles and mates with a copper pad area on the PCB for thermal management of repetitive transients.
Protection window and board-level fit
The unidirectional channel (single) is polarity-sensitive — the cathode band on the package must face the positive rail. Operating temperature spans -65°C to 150°C junction, covering the full industrial and most automotive under-hood ambient ranges.
