I use the below relay driver circuit.
The relay is 5V @ 108mA rated (~46 ohm coil resistance).
I would like to use another protection diode accross the BJT.
What diode should i choose?
What happen if the diode will go into forward state when 5V is applied on it? (when BJT is in cut-off).
Wouldnt the diode cause the relay to have current (5-0.7)/46 to flow through it?
