Product details

What the 1.5 kW rating means for a 25.6 V rail

The 1.5SMC30AHM3/H: For a 24 V nominal automotive bus that sees load-dump or inductive kickback, the 25.6 V standoff sits above the steady-state rail so the diode stays dark until the transient arrives.

AEC-Q101 and the operating envelope

AEC-Q101 qualification means this part passed the automotive-grade stress suite: temperature cycling, high-temperature reverse bias, and humidity bias at 85 °C/85 % RH. No power line protection (the part is unidirectional, not a steering diode array), so it is a single-event clamp, not a rail-to-rail ESD protector.

The base product number 1.5SMC30 covers the full family, so the suffix AHM3/H identifies the AEC-Q101 qualified, halogen-free variant in tape-and-reel packaging.

Frequently asked questions

What compliance documentation does Vishay provide for 1.5SMC30AHM3/H?

As an AEC-Q101 qualified part, Vishay provides an automotive-grade PPAP package upon request, including the qualification test report and the PCN (process change notification) history. The part is halogen-free per the AHM3/H suffix. Standard RoHS and REACH compliance declarations are available from Vishay's documentation portal.
