The 1.5SMC22CAHM3/H: Maximum clamping is 30.6 V at the rated current, which keeps the protected node within the typical 36 V abs-max of downstream ICs.
The cathode band on the body marks orientation, but since this is a bidirectional device, polarity does not matter; you can install it either way and it still clamps both polarities.
Listed as Active by Vishay.
The part is AEC-Q101 qualified for automotive use and carries the TransZorb® designation.
