1500W bidirectional clamp for 28V rails
The 1.5SMC33CA_R1_00001: The clamping voltage maxes out at 45.7V at the rated peak pulse current of 33A, meaning the downstream silicon — a DC-DC converter input or a sensor supply — sees a hard voltage ceiling well below its 60V abs-max. The breakdown voltage min of 31.4V gives a 3.2V guard band above the standoff rail before the TVS starts conducting leakage current.
DO-214AB footprint and temp range
The bidirectional channel means a single device clamps both positive and negative transients, saving a board revision versus placing two unidirectional diodes back-to-back. No power line protection built in — this is a signal-rail or low-voltage supply clamp, not a mains-side MOV replacement.
No NRND flag, no last-time-buy notice — the part is a current catalog item.
