Product details

What the clamping chain means for your protection circuit

The 1.5SMC82AHM3/H: The 70.1 V reverse standoff (typ) is the working rail the diode monitors without conducting — the protected node runs at or below this level under normal operation. 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.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC82AHM3/H in this Circuit Protection family?

The 1.5SMC82 base number is shared across the 1.5SMC series, so a pin-to-pin alternate within the same family is a plausible second-source search — but no official cross-reference or approved second source is listed in the current record. 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.

What compliance documentation does Vishay General Semiconductor - Diodes Division provide for 1.5SMC82AHM3/H?

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. The series name TransZorb® also carries the Vishay trademarked construction — confirm with your Vishay rep whether a specific CoC or REACH/RoHS declaration is available at the order-code level for automotive customer submissions.
