The 1.5SMC22AH: The 18.8 V reverse standoff (working voltage) means it sits across a 12 V or 15 V rail without conducting leakage; clamping starts at 20.9 V breakdown and hard-limits at 30.6 V with a 51 A peak pulse current capability.
AEC-Q101 qualification puts this part in the automotive-grade bin — the same stress screening (HTRB, H3TRB, temperature cycling) used for engine-ECU and body-control modules.
The part carries AEC-Q101 automotive qualification, which includes the semiconductor stress-test battery per that standard. RoHS and REACH compliance are standard for the 1.5SMC series, though specific certificates should be confirmed at order.
