The 9.5A peak pulse current rating means it handles moderate-energy surges from relay coils, solenoid drivers, and alternator field dumps without exceeding the junction temperature limit. ## Automotive-grade qualification for under-hood reliability AEC-Q101 qualification certifies the part for automotive stress grades — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive discrete semiconductor standard. The -55°C to 150°C junction temperature range covers the full under-hood thermal profile, from cold-crank winter starts to the heat soak near the exhaust manifold. ## DO-214AB package and PCB footprint Supplied in the DO-214AB (SMC) package, a standard surface-mount footprint shared across the 1.5SMC family. The large copper tab on the cathode side conducts heat into the PCB copper plane — the 1500W peak pulse rating assumes a low-thermal-resistance layout with adequate pad area and thermal vias under the tab. Tape-and-reel packaging suits automated pick-and-place assembly. No power line protection feature — this is a standard TVS for unidirectional transient clamping, not a rail-to-rail steering diode array.","metaTitle":"1.5SMC120AHM6G TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"1.5SMC120AHM6G Zener TVS diode, 1500W peak pulse, 102V standoff, 165V clamp.
