Product details

1500W surge clamp for 30.8V rails

The 1.5SMC36AHM3/I: When a surge exceeds the breakdown threshold (34.2V min), the device clamps the overvoltage to 49.9V max, shunting the surge current through the diode rather than the downstream circuitry.

AEC-Q101 and TransZorb construction

This part carries AEC-Q101 qualification, meaning it has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the JEDEC standard for discrete semiconductors. The TransZorb® process yields a planar passivated junction that holds the breakdown voltage stable over temperature and surge life.

Frequently asked questions

What compliance documentation does Vishay provide for this part?

As an AEC-Q101 qualified device, Vishay supplies a PPAP (Production Part Approval Process) package upon request, including the qualification test report and RoHS/REACH compliance declarations. The part is RoHS-compliant and free of conflict minerals per Vishay's standard documentation.
