What the 1500 W peak pulse rating means for your protection design
The 1.5SMC15AH: That 1.5 kW rating tells you the device can absorb a single surge event up to that energy without failing short — but the real fit decision comes from the clamping voltage and standoff numbers. The clamping voltage maxes at 21.2 V at the rated peak current of 74 A — that clamp sets the voltage the downstream circuitry must survive.
Graded as Automotive and qualified to AEC-Q101, this TVS is built for the reliability screening and temperature cycling that under-hood and chassis-mounted electronics demand. The DO-214AB (SMC) package is a standard surface-mount footprint for TVS diodes in this power class — the same pad layout used across the 1.5SMC series, so a board already routed for a sibling part accepts this one without a layout change.
