Don't know why you say that Alec.No. The top diode would make the lower diode useless in killing back-emf spikes.
The turn-on time of a normal silicon junction diode is very fast, which is what is needed for this applicationDon't know your switching speeds but a schotky diode may help if your diode isn't fast enough. ..............
I wasn't thinking, its not like you are going to be switching relays in nanoseconds.The turn-on time of a normal silicon junction diode is very fast, which is what is needed for this application
Their turn-off can exhibit a long reverse-recovery time, which a Schottky doesn't have, but that's not an important characteristic for a diode use for transient protection across an inductance.
Of course not.I wasn't thinking, its not like you are going to be switching relays in nanoseconds.
