From a rework standpoint, the SMC body is large enough that a standard hot-air nozzle at 300°C will reflow the solder joints without cooking the adjacent passives. The cathode band is clearly marked on the body — orientation is unambiguous under a microscope. Will it survive the hot air? Yes, as long as the board has a thermal relief on the cathode pad to keep the heat from sinking into the plane. AEC-Q101 compliance is the key authority signal for automotive procurement — it certifies the part meets the stress-test sequence defined by the Automotive Electronics Council for discrete semiconductors. The TransZorb® designation is Vishay's proprietary TVS technology, not a generic Zener; the avalanche response is tighter than a standard Zener's for surge clamping.","metaTitle":"Vishay 1.5SMC250AHM3_A/I TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"Active Vishay 1.5SMC250AHM3_A/I Zener TVS diode, 1500W peak pulse, 214V standoff, 344V clamp.
