Bt136 Circuit Diagram. This simple traic circuit bt136 and opto coupler moc3021 can able to control high voltage devices from microcontroller. The bt136 is triac with 4a maximum terminal current.
Is 10 nf 250 v sufficient or should i use 400 v. It also provides galvanic isolation between high and low voltage part u can. Is the value of 100 ohm 1 watt correct on pin 6 of moc3021.
It also provides galvanic isolation between high and low voltage part u can.
High caution is needed while working with ac power supplies the operating voltage is stepped down for safety purpose the standard ac power of 230v 50hz in india is stepped down to 12v 50hz using a transformer. For example arduino to control 230 220v bulb or any device which runs on high voltage. Bt136 bt136 o c n b bt136 o hf n b function. The bt136 is triac with 4a maximum terminal current.
