    I use a 1.5KE24CA to keep those nasty transient spikes (like a relay opening) out of my automotive stuff. Anything over about 24 volts is clamped.

    I've worked in the US Auto industry for over 20 years and standard procedure
    these days is to use a TVS. They are quite durable. Zener diodes can't handle
    the current of a large spike. I use a 24 volt TVS in everything that I design for
    automotive use.

    Yes, 12 volt systems. For 24 volt systems, I would use a 33 or 36 volt TVS.
