I know the common practice is to use a capacitor in a switching circuit clean up the signal and control emf noise, I am just curious If a zener diode would have a similar effect. does anyone use them in there switching circuits, I know relays use diodes to shunt the coil. other than that is there any practical reason to use them, I have not used them in any of my circuits, and am wondering If I should be using them? I only used a regular diode on the main input in case I am stupid enough to hook up backwards. Thoughts?
