AEC-Q101 qualification certifies it for automotive stress levels — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive discrete semiconductor standard. ## Clamping voltage and pulse current Maximum clamping voltage is 45.7V at the 32.8A peak pulse current. For a 24V system with a 36V load-dump transient, this TVS holds the line below the 50V abs-max of downstream DC-DC converters. Single unidirectional channel means one device protects one rail. ## DO-214AB SMC package and rework DO-214AB (SMC) package — the larger of the standard surface-mount TVS footprints. Polarity is marked by the cathode band — easy to verify under magnification before reflow. Supplied in Tape & Reel — compatible with standard pick-and-place. ## Active production and sourcing Listed as Active — Vishay continues to manufacture this part.","metaTitle":"Vishay 1.5SMC33AHM3/I TVS, 1500W, 28.2V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC33AHM3/I automotive AEC-Q101 Zener TVS diode, 1500W peak pulse power, 28.2V standoff, DO-214AB SMC.
