This means a 24 V automotive rail sees the clamp voltage stay within the downstream IC's absolute-maximum rating — a key parameter for ECU and sensor supply protection. The part is qualified to AEC-Q101, the automotive discrete semiconductor stress test standard, covering temperature cycling, ESD, and reliability screening for -65 °C to +150 °C junction operation. That temperature range suits under-hood and engine-bay deployment where ambient can exceed 105 °C. Housed in a DO-214AB (SMC) package, the device is surface-mount with a standard footprint shared across the 1.5SMC family. The supplier device package is also designated DO-214AB (SMCJ), so the land pattern is consistent across Vishay's SMCJ and 1.5SMC series. Tape-and-reel packaging (TR) supports automated pick-and-place assembly.","metaTitle":"1.5SMC20AHE3/57T Vishay TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"1.5SMC20AHE3/57T Vishay Zener TVS diode, 1500W peak pulse, 17.1V standoff, 27.7V clamp, DO-214AB, AEC-Q101 automotive grade.
