Product details

1500 W peak pulse in a DO-214AB footprint

The 1.5SMC11AHM3/H: A single 1500 W peak-pulse Zener TVS in the DO-214AB (SMC) package, qualified to AEC-Q101 for automotive stress levels. The 9.4 V standoff voltage sits below a 12 V battery rail, clamping at 15.6 V during a 96.2 A, 10/1000 µs surge — the clamp voltage stays within the 20 V abs-max of downstream 12 V-rated ECUs. Unidirectional only — one channel per device.

AEC-Q101 and the TransZorb® series

Part of the 1.5SMC TransZorb® family, which Vishay markets for telecom and automotive transient protection. The AEC-Q101 qualification means the part has passed the full automotive discrete reliability suite — temperature cycling, HTRB, autoclave, and ESD — and carries PPAP-level traceability on the wafer lot and assembly date code.

Frequently asked questions

What compliance documentation does Vishay provide for 1.5SMC11AHM3/H?

As an AEC-Q101 qualified part, Vishay provides PPAP documentation, a radiation test report is not part of the standard qualification. RoHS and REACH declarations are available from the manufacturer's documentation portal for this order code.
