Back EMF question
«
on:

Does anyone know if IN914 diodes will block back EMF?
Also, do they need to be on both the positive and negative side of a 12 volt DC circuit.
Thanks!

They only need to be on one side but the 914s will only handle an Amp (max) of forward current.

I suggest diodes fron the 1N400x family there very common, cheep and very robust, I have a drawer full of the 1n4007's which are one amp 1KV that I use for everything.

I really wouldn't suggest using a 1N914 for anything other than logic purposes. That is a pretty wimpy diode, mechanically and electrically, that is only rated at 200ma.
