1500W bidirectional clamping for 94V rails
The 1.5SMC110CAHM3/H: The 105V minimum breakdown voltage ensures the diode stays off during normal operation but fires before the downstream silicon sees damaging overvoltage. At 9.9A peak pulse current, the clamping voltage stays under 152V — the scorch mark tells you this part took the hit so the ECU or BCM didn't.
AEC-Q101 and the -65 to 150°C operating envelope
The -65°C to 150°C junction temperature range covers under-hood and engine-bay environments where the ambient soaks above 105°C on a hot day. This is a current-generation part you can spec into a new design without worrying about an EOL clock ticking.
DO-214AB SMC footprint and board integration
Housed in the DO-214AB (SMC) package, the 1.5SMC110CAHM3/H is a surface-mount device with a standard footprint shared across the 1.5SMC family. The bidirectional configuration uses a single device where a unipolar design would need two diodes back-to-back — saves board space and reduces the component count on the clamp rail. The Tape & Reel packaging suits automated pick-and-place for high-volume automotive lines. No power line protection feature (the diode is a standalone transient suppressor, not a combined filter/clamp device).
The active lifecycle means no end-of-life inventory constraints — this part is a standard catalog item.
