The typical reverse standoff of 6.4V sits above the 5V rail, keeping the device off during normal operation without clamping a healthy 5V logic line. When a transient does arrive, the 11.3V maximum clamping voltage at peak pulse determines what the protected load actually sees. For a 5V rail that is a comfortable 2.3× margin over working voltage, well within most downstream IC abs-max ratings. Peak pulse current of 139A at 10/1000µs is a high-energy transient rating — the 10/1000µs waveform shape means the device must survive a 10µs rise and 1000µs fall, not a narrow nanosecond spike. This rating and the 1500W peak pulse spec together confirm the part is sized for automotive load-dump and other ISO 7637-2 transients, not just ESD-level events. The 6.4V standoff sits below a 12V automotive rail — a 12V line with normal transients will exceed standoff and reach breakdown, so this part is better suited to 5V logic rails or sensor lines fed from the 12V domain through a regulator. Confirm the rail voltage before committing to the BOM line. ## Automotive qualification and temperature range AEC-Q101 qualification means the part passed the automotive stress tests for discrete semiconductors — temperature cycling, humidity bias, ESD, and mechanical shock per the AEC-Q101Rev-D profile. This is the baseline for under-hood and chassis-domain deployments, not a generic commercial screening. Junction temperature rated -55°C to 150°C spans the full automotive temperature band. Cold soak at -55°C covers cold-start conditions; 150°C junction covers under-hood ambient at the high end, though the actual margin above ambient depends on board thermal design and local heating from the load-dump event itself. The 7.13V minimum breakdown gives a tight 0.73V window between the 6.4V typical standoff and the activation point — this matters for precision 5V rail protection where unintended early triggering on noise or ripple becomes a concern. ## Package, polarity, and BOM fit The DO-214AB (SMC) package is the standard SMB footprint used across the 1.5SMC family — compatible with standard SMA pads with the wider body clearance. Bidirectional polarity means no orientation concern on the PCB; both polarities of transient are protected without the reversed-diode placement rule that applies to unidirectional parts. Surface-mount, tape-and-reel packaging fits standard SMT assembly flow for ECU and module boards. The AEC-Q101 grade does not alter the package footprint or solder-profile window relative to the commercial 1.5SMC family.","metaTitle":"1.5SMC7.5CAHM6G TVS Diode, 1500W Peak, AEC-Q101","metaDescription":"AEC-Q101 Zener TVS diode, bidirectional, 6.4V standoff / 7.13V breakdown / 11.3V clamp at 139A peak pulse.
