Breakdown occurs at 114V minimum, clamping at 165V maximum at the 9.1A peak-pulse current (10/1000µs waveform). That 165V ceiling keeps downstream 150V-rated MOSFETs and ASICs inside their safe operating area during a surge. ## Package and board-fit DO-214AB (SMC) surface-mount package — the same footprint as standard SMC diodes. The cathode band marks the unidirectional polarity; the single-channel device clamps one rail per package. Operating junction temperature spans -65°C to 150°C, covering the full automotive ambient range with margin for self-heating during repetitive surge events.","metaTitle":"1.5SMC120AHM3/H Vishay TVS, 1500W, 102V, DO-214AB","metaDescription":"Vishay 1.5SMC120AHM3/H Zener TVS, 1500W peak pulse, 102V standoff, AEC-Q101 automotive, DO-214AB.
