Hi,
I'm building a circuit that runs on 12VDC however needs to have the ability to sense when a higher voltage occurs (say 15v or so) and turn on a relay to divert power via a 12v regulator IC. I was considering a 12v zener to opperate the relay, which works, but I'm concerned about how long the zener would last in a full time 24v situation. Any help would be much appreciated!
Cheers
Josh
