The .05 capacitor is not optional but is vital for the operation of the moc3023. In my circuit the capacitor fires at 29 volt providing 80ma of current to the gate of the main triac.

The 360 ohm resistor shows 2.7w of instant power and the 470 ohm 3.6 watts. However the average power is very low being less than 0.25 watts.

I initially used a 560 ohm 3 watt resistor without the capacitor and it burnt out.

Use a 3 watt resistor for the 360 and 470 ohm resistors to be on the safe side.

I hope this will assist other uses of the moc3023.
