The SMBJ22AQ-13-F: The 22V reverse standoff voltage means it starts clamping above the 24.4V breakdown minimum, and the maximum clamping voltage at 16.9A peak pulse current is 35.5V — that gives you the protection window for a 24V nominal automotive rail. No power line protection (it is a Zener, not a steering diode array), so keep it on the signal or low-side power rail.
