It clamps transients on a 25.6 V nominal rail, with a breakdown voltage of 28.5 V min and a clamping ceiling of 53.5 V at the rated current. The single bidirectional channel handles 187 A peak pulse current at the 8/20 µs waveform, sized for load-dump and inductive kickback on automotive 24 V buses.
The base product number is SM15T30, and the 'CAY' suffix denotes the bidirectional, AEC-Q101 variant.
Yes, the SM15T30CAY is listed in the Automotive, AEC-Q101 series. The part has passed the automotive-grade stress tests required for under-hood and chassis applications.
