A ambrose New Member Dec 17, 2003 #1 i want to drive a small 5.3W to 7W appliance 230v what value of triac should i use. is there any other way without triac and relay this is a timer.

Sebi Active Member Dec 17, 2003 #4 Try with MOC3041 optotriac. It is designed for zerocross switching with triac, but the enabled dissipation 150mW, and You need only about 30mA.

A ambrose New Member Dec 17, 2003 #5 actually i used BT134 . i didnt isolate it using optoisolator is it enough to useMOC3041 or we have to connect a triac to it the cost of moc type is high

Sebi Active Member Dec 18, 2003 #6 You should also use 2N6075A or B from ON semi in smaller package (TO225AA) and with sensitive gate, but - i mean - the optotriac also can work without another triac for 7W load.

A ambrose New Member Dec 18, 2003 #7 hai sebi what i saw in the data sheet of 2N6073 TRIAC is it can be directly connected to a CMOS circuit .shall i use it . also is there a possibility to use transistor instead of triac
