1.5kW Zener TVS for 13.6V rails — AEC-Q101 qualified
The 1.5SMC16AHM3_A/I: It provides 1500W peak pulse power dissipation across a 10/1000µs waveform, making it suitable for protecting 13.6V nominal DC rails from load-dump and surge transients. Rated for automotive and telecom applications, this part carries AEC-Q101 qualification — the automotive industry's stress test for semiconductor reliability under temperature cycling, high-temperature reverse bias, and ESD. The -65°C to 150°C junction temperature range covers under-hood engine bay conditions and outdoor telecom cabinet thermal profiles. Minimum breakdown voltage is 15.2V, with a reverse standoff of 13.6V — the protection window starts conducting above the standoff and fully clamps before the breakdown threshold, keeping downstream silicon below its absolute maximum rating.
DO-214AB (SMC) package and board integration
The base product number 1.5SMC16 covers the full voltage variant family; the HM3 suffix denotes the AEC-Q101 automotive grade and the _A/I suffix indicates the specific lead-free plating and packaging code.
Sourcing and lifecycle — active production
For a pin-compatible alternative within the same family, the 1.5SMC series includes other voltage variants in the identical DO-214AB footprint — a BOM position change requires only a different order code, not a PCB layout revision.
