How to drive a MOSFET with an optocoupler? - Stack Exchange

Why can't I use an optocoupler to drive an AC circuit using the arduino digital pins? I was wondering what would happen if I used an optocoupler like 4n35 to drive an AC circuit. Will the phototransistor inside the chip burn out? I use MOC3020 + BT138 + 330 and 510 Ohm resistors. It works good as relay and in dimmer scheme. Scheme is

Learn how to set up a 5V relay on the Arduino use sensors to control 120-240V appliances. The Arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30 C. Use “solid state relay” assembly or transistor+optocoupler instead. Reply. Anika on
