With a 23.1V reverse standoff voltage, it sits on 24V nominal power rails — the typical battery line in trucks, buses, and off-highway vehicles — and clamps transients to 37.5V before the downstream electronics see damage. Peak pulse power is 1500W (1.5kW) under the 10/1000µs waveform, corresponding to a 40A peak pulse current. That rating covers load-dump events from alternator field decay and inductive kick from solenoids or relays on the same bus. ## Package and thermal integration The SMC footprint is standard for 1500W-class TVS diodes — the large copper pad on the cathode side sinks pulse heat into the PCB plane. The tape-and-reel packaging (TR) suits high-volume pick-and-place assembly.","metaTitle":"Vishay 1.5SMC27AHM3/H TVS Diode, 1500W, DO-214AB","metaDescription":"Active AEC-Q101 Zener TVS, 1500W peak pulse power, 23.1V standoff, 37.5V clamp, DO-214AB.
