Re: Silicon Controlled Rectifier

Can you please post the part numbers you are proposing? I couldn't read them very well in the jpg.

I'm not sure what all the diodes next to the coil are for. You just need a single diode in anti parallel to the coil.

If you are using a single SCR, you can ignore what I said about ballast resistance. Just the gate resistance is necessary.
