1500 W bidirectional clamp for 40 V rails
The 1.5SMC47CAHM3/I: A single bidirectional channel handles both positive and negative transients, which simplifies board layout when the signal or power rail swings relative to ground.
AEC-Q101 and 150 °C junction rating
This part carries AEC-Q101 qualification, the automotive-grade stress and reliability standard for discrete semiconductors.
DO-214AB SMC footprint and peak current
The SMC body provides a larger copper pad area than the smaller SMA/SMB siblings, which helps spread the transient heat into the PCB copper. No power line protection is built in — this is a dedicated transient suppressor, not a combined filter. The tape-and-reel packaging suits automated pick-and-place for volume builds.
