hi there,
Hi there, Thank you for your reply.The led or general resistance load don't need the diode, because they won't generate
the emf.
What kinds of diode you want to use, that is considering about the frequency, as relay is a low speed active parts, so you can using a 1N4000~4007, it depends on the voltage of relay, I will choosing 1N4007 and I just buy that one, because I don't have to worry about which one is 1n4001 or some others when they mixed together.Hi there, Thank you for your reply.
Yes that was what I was thinking and the circuit is actually from the actual product schematic. I found that S1D diode is a rectifier. Could that diode be used for filtering purpose?
deIs it a small signal diode, a rectifier diode OR, a Zener diode. Check the part number, find the datasheet and report back. A Zener diode limits the voltage - and would be cathode to Vcc as in your circuit.
