In this circuit,pressing on sw1 will trigger the scr and the led(10mA)will turn-on.
In order to turn off the scr(and the led),i use a bjt transistor,which bypass the scr.
I understand that when the transistor will be saturated(0.2Vce)all the current will bypass the scr and the scr will turn-off.My question is:What is the max Vce value that i can plan for the transistor which will still be able to turn-off the scr?(/making the current flow through it and not through the scr?).
