AEC-Q101 qualified, 1500 W peak pulse — the automotive transient clamp
The 1.5SMC12CAHR7G: The AEC-Q101 stamp means this part passed the full automotive stress suite — temperature cycling, HTRB, H3TRB, and ESD — with PPAP documentation available. For an ECU, BMS, or sensor module exposed to load-dump, alternator field-decay, or inductive kickback, the 1500 W rating provides a comfortable margin above the typical 8/20 µs surge levels in 12 V and 24 V vehicle electrical systems.
Bidirectional clamping on a 10.2 V rail
The minimum breakdown voltage is 11.4 V, so the device does not conduct during normal operation on a 10.2 V rail. The clamping voltage of 16.7 V at 94 A peak pulse current means the protected downstream silicon sees less than 17 V even during a severe surge — well within the absolute maximum rating of most 12 V-rated ICs. The single bidirectional channel clamps both polarities with one device, saving board area versus two unidirectional diodes in anti-series. The DO-214AB (SMC) package handles the 1500 W pulse without exceeding the rated junction temperature when the copper pad area follows the recommended land pattern.
Active production, AEC-Q101 documentation on file
Taiwan Semiconductor Corporation is the brand and sole source. The AEC-Q101 qualification package includes the full PPAP documentation set that an OEM auditor will request. No official second-source or pin-compatible cross-reference is listed on this record.
