The clamping ceiling is 92 V at the rated 16.3 A peak pulse (10/1000 µs waveform), which is the number the downstream IC's abs-max rating must stay below. ## AEC-Q101 qualification and thermal margin AEC-Q101 is the discrete-semiconductor counterpart to AEC-Q100 — it certifies the part passed temperature cycling, HTRB (high-temperature reverse bias), and mechanical stress screening at the component level, not just the device-level screen. That is the baseline an OEM auditor in Tier-1 automotive asks for. Budget the actual TJ against the clamping event power dissipation using the Zener impedance in the datasheet — at 16.3 A the clamping voltage is not zero, and the dissipation pulse must clear before TJ exceeds 150 °C.","metaTitle":"Vishay 1.5SMC68CAHE3/9AT, 1500W TVS Diode, AEC-Q101","metaDescription":"Vishay 1.5SMC68CAHE3/9AT bidirectional TVS Zener, AEC-Q101 qualified, 58.1V standoff, 92V clamping, 1.5kW peak pulse, DO-214AB SMC.
