Hello
When connecting a power transistor to a ignition coil how is it possible to stop back emf.
Placing a diode across the emitter and collector or use a zener diode across the emitter and collector.
This circuit is very popular but usually there is so many problems with it as due to back emf destroying the lm555 or the transistor or both.
Thanks EAI
