The large tab area on the SMC body helps conduct pulse heat into the PCB copper — keep the pad size per the Vishay application note to stay within the 1500 W derating curve. No power-line protection (unidirectional Zener only), so it clamps one polarity — use it on a single-rail bus where the transient is positive-going relative to ground.","metaTitle":"1.5SMC18AHM3/I Vishay TVS Diode, 1500W, 15.3V Standoff","metaDescription":"Active Vishay 1.5SMC18AHM3/I Zener TVS diode, 1500W peak pulse power, 15.3V reverse standoff, AEC-Q101 qualified.
