Clamping and peak pulse ratings
The 1.5SMC9.1AHM6G: The 7.78 V typical reverse standoff is the working voltage at which the device sits idle in normal operation; it begins conducting when the line exceeds the 8.65 V minimum breakdown threshold.
Automotive grade and thermal range
AEC-Q101 qualification places this in the automotive electronics qualification flow — temperature cycling, humidity bias, and surge testing are run to the stress levels required by the automotive ecosystem.
