Active production — no end-of-life risk for this BOM line
The 1.5SMC16CAHM3/I: For a BOM already qualified on this TVS, there is no forced migration to a substitute.
With a 13.6 V reverse standoff voltage, this TVS sits across a 12 V nominal battery line without conducting during normal operation. The 15.2 V minimum breakdown triggers clamping before the rail exceeds the downstream IC's abs-max rating. The 22.5 V clamping voltage at 66.7 A peak pulse current (10/1000 µs waveform) absorbs load-dump and inductive kickback events common in automotive and telecom power buses. The 1500 W peak pulse rating matches the 1.5SMC family's standard power envelope for this package.
AEC-Q101 grade — what it means for underhood qualification
The -65°C to 150°C junction temperature range covers underhood ambient and self-heating during a transient event.
DO-214AB (SMC) package — board-fit note
The copper pad area under the cathode tab sets the thermal resistance for pulse power dissipation; a 2-oz copper plane on the PCB improves the SOA during repetitive surges. Tape-and-reel packaging (per) supports automated pick-and-place for volume assembly. No special moisture sensitivity level is flagged — standard MSL handling applies.
