Would that be a 'sidactor'? This variant works for AC limiting, should be OK with a polyfuse in series about not hurting a 24 supply
It has to be depowered completely to reset it, so the polyfuse will stay warm until unplugged. The breakover is built-in, rather coarse, so one hopes your nominal 12V box is OK with 15...

Of course, but you can do it in some of the simulators.
A soft gate drive, like just a zener, can make an SCR chip fire locally, near the gate wirebond, and fry that region before conduction spreads laterally. It's like 2nd breakdown failure in transistors.
There are specific crowbar controller chips to make a hard, fast gate drive.
Look it up.
I once mightily abused an LM317 adjust pin to see if I could break it. No feasible abuse did.
100 uF ADJ bypass, 30V output, short input to ground. That'll do it.
