I am using an Opto-coupler to trigger a BT136-600 TRIAC. I need to supply some 15ma to trigger the gate.I have connected everything perfectly and I am giving the required current. But my TRIAC is not triggering. Pls help me. The project is Under/Over voltage protection using SSR. I am using LM339 and an Op-amp to input the base of the photo transistor of the optocoupler.
