It clamps transients on a 102V nominal rail — the reverse standoff voltage — and breaks down at a minimum of 114V before clamping at 165V maximum with a 9.1A peak pulse current (10/1000µs waveform). ## Peak pulse power and clamping in context The 1500W rating (1.5kW) is the peak pulse power dissipation for an 10/1000µs exponential waveform — the standard telecom and automotive surge shape. At 165V clamp, the 9.1A peak pulse current is the maximum the diode can handle before the junction temperature exceeds the 150°C limit. For a 24V or 48V automotive bus, this part sits on a 102V rail (e.g., a high-voltage battery line or a DC-DC converter output), not a 12V system. ## Package and board-fit for reflow Housed in DO-214AB (SMC), a standard surface-mount package with a JEDEC footprint. The copper tab on the cathode side conducts heat to the PCB pad — the board copper area sets the thermal resistance for repetitive pulse trains. Tape-and-reel packaging (TR) feeds directly into a pick-and-place line; no special handling beyond the standard MSL level for this package type.","metaTitle":"1.5SMC120AHM3_A/I Vishay TVS Diode, 1500W, AEC-Q101","metaDescription":"Vishay 1.5SMC120AHM3_A/I automotive TVS, 1500W peak pulse, 102V standoff, AEC-Q101 qualified.
