I have been using the moc3023 random phase opto to try to turn on a triac. It has been turning on the triac at full power. I have tried the snubberless bta16-600cw triac . Still getting full power on the load.
I have been turning on the emitter side of the opto at 5ms after zero crossing. I am using 5 volts here. I measure a dc voltage of about 2.5v which would be the correct average if the 5v signal is applied at half way through a half cycle of the mains.
The recommended triac snubber is a 39 ohm resistor and .01uf capacitor. I used a .047 uf capacitor as I do not have the .01 at the moment. This didn't work. I then tried the opto snubber of a 470 ohm resistor and .047 capacitor. I blew a 1/2 watt resistor. Probably need a 5w here.
Before I get the correct recommended parts does anybody have a PROVEN circuit with the moc3023 for turning on the triac with no false triggering? This would include a suggested triac and snubber components and their ratings.
The capacitors of course have to be mains rated.
