1500 W peak pulse, AEC-Q101 qualified
The 1.5SMC16AHM3/I: The single unidirectional channel targets DC power rails and signal lines in automotive ECUs, telecom line cards, and industrial control boards where a single transient event can exceed the IC's abs-max rating.
Breakdown and clamping window
Minimum breakdown voltage is 15.2 V, with the reverse standoff (working voltage) at 13.6 V — the device stays transparent below that rail and only conducts when the transient pushes the line above the breakdown threshold. Maximum clamping voltage at the rated 66.7 A peak pulse current is 22.5 V, giving a 9 V window between the working rail and the clamp ceiling; this margin determines whether a 24 V-tolerant IC survives a load-dump transient on a 12 V bus. Operating temperature spans -65 °C to 150 °C junction, covering the full automotive under-hood range and telecom outdoor cabinet extremes without derating the pulse power capability.
DO-214AB (SMC) package and mounting
Supplied in DO-214AB (SMC) surface-mount package, the same footprint as standard SMC diodes — the copper tab on the cathode side is the primary thermal path, so the PCB pad area under the package sets the junction-to-ambient thermal resistance for repetitive pulse trains.
No pin-compatible second-source from Vishay's own 1.5SMC family is listed as a direct cross, but the base product number 1.5SMC16 covers multiple suffix variants — confirm the specific AEC-Q101 and packaging suffix before substituting.
