Higher peak currents in shorter waveforms (8/20 µs) are addressable only if the design uses a higher-peak-rated series in the same SMC footprint; the 1.5SMC family splits peak-pulse capability across its voltage-tier variants. At 1500 W peak pulse the device dissipates enough to protect alternator load-dump events on the 12V rail without cascading upstream. The minimum breakdown of 7.13 V sets the lower bound of the clamping window — below that voltage the TVS does not conduct, so normal rail noise does not trigger spurious clamping. ## AEC-Q101 qualification and thermal margin for under-hood deployment The 1.5SMC series carries AEC-Q101 automotive qualification — this means the part has passed the mandatory temperature cycling, humidity bias, and surge-life stress tests defined for discrete semiconductors in automotive environments. ## DO-214AB SMC package and surface-mount assembly notes The DO-214AB (SMCJ) package is the industry-standard surface-mount TVS footprint — the cathode bar on the body identifies the polarity direction, which must match the unidirectional protection orientation on the board. Delivered on tape-and-reel per EIA-481, it is compatible with standard high-speed SMT pick-and-place lines without special tooling.","metaTitle":"Vishay 1.5SMC7.5AHE3/9AT TVS Diode, 11.3V Clamping","metaDescription":"AEC-Q101 automotive Zener TVS, 1500W peak pulse, 133A peak pulse current, DO-214AB SMC.
