The supplier device package is listed as DO-214AB (SMCJ), which is the same JEDEC outline — no footprint change between the two designations. ## AEC-Q101 qualification and automotive deployment The AEC-Q101 qualification and Automotive series designation mean the part has passed the stress tests (HBM ESD, temperature cycling, high-temperature reverse bias) required for under-hood and cabin electronics. The operating temperature range of -65°C to 150°C covers the full automotive thermal profile, from cold crank to engine-bay soak.","metaTitle":"1.5SMC30AHE3/9AT TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC30AHE3/9AT unidirectional TVS diode, 1500W peak pulse power, 25.6V standoff, 41.4V clamp.
