What matters on the BOM line is whether the clamping voltage at your specific Ipp stays below the downstream IC abs-max — the 113 V ceiling at 13.3 A is the spec to compare against the protected load's rating, not a typical or derated figure. ## Automotive grade and thermal margin The AEC-Q101 qualification means it has passed the temperature cycling, humidity, and surge stress sequence that distinguishes an automotive discrete from a commercial TVS, and the 1.5SMC base part number confirms it carries the automotive process flow rather than the standard 1.5SMCxx commercial grade. The TransZorb® construction — the original Vishay gated-arc-avalanche design — provides a defined clamping characteristic that a plain Zener does not, which is why sourcing the exact series suffix matters for repeatability across production lots.","metaTitle":"Vishay 1.5SMC82AHM3/H Zener TVS Diode, 1500W, 70.1V","metaDescription":"Vishay 1.5SMC82AHM3/H, AEC-Q101 automotive Zener TVS in DO-214AB (SMC), 1500W peak pulse, 70.1V standoff, 77.9V breakdown.

Confirm the standoff voltage and peak pulse rating match before substituting, since a commercial-grade 1.5SMC part may not carry the AEC-Q101 automotive process flow the BOM specifies."},{"question":"What compliance documentation does Vishay General Semiconductor - Diodes Division provide for 1.5SMC82AHM3/H?","answer":"The AEC-Q101 qualification is listed as part of the series designation — this is the automotive IC/discrete stress test package (temperature cycling, humidity bias, surge life) that OEM quality teams typically request in a PPAP or IMDS submission.
