The AEC-Q101 qualification means it is screened for automotive reliability — under-hood temperature swings and transient immunity per the automotive electronics council standard. ## Protection window and thermal margin The minimum breakdown voltage is 44.7V, giving a 4.5V guard band above the 40.2V standoff — enough to ride through normal bus ripple without nuisance clamping. The clamping voltage at 23.1A peak pulse is 64.8V, which stays below the typical 70V abs-max of downstream 48V-rated ICs. ## DO-214AB SMC footprint and reflow Housed in a DO-214AB (SMCJ) surface-mount package, the part mates with a standard SMC footprint. Tape-and-reel packaging suits automated pick-and-place; the reel quantity is typically 3500 pieces per 13-inch reel. For BOM planning, the base product number 1.5SMC47 covers the full family; the HE3 suffix denotes the AEC-Q101 automotive grade.","metaTitle":"1.5SMC47CAHE3/9AT Vishay TVS, 1500W, 40.2V, DO-214AB","metaDescription":"Vishay 1.5SMC47CAHE3/9AT bidirectional TVS, 1500W peak pulse, 40.2V standoff, AEC-Q101 automotive grade.
