The 3021 and 3041 are of exactly the same size. How will you save space unless you go for SMD versions? Ok...another thing..you cant use 3041 as it is a zero crossing opto. Instad on 3021, 3011 is quite suitable if you dont get the later.alvinthen said:btw, is it ok if i use MOC 3041 to save space?
i'm still struggling at which optocoupler and triac to choose

Yes absolutely correct. Just swicth on the Opto when to ON the AC load, and swicth OFF the opto to switch off the AC load. As told by Brian, the triac inside the opto is not capable of handling a load. Thus external is a safer way to choose.alvinthen said:hmm.. i tot i could use the triac built inside the 3041 so i could save space by reducing one triac.. anyhow i still need one "external" triac?
i still dunno how to control the triac, do i just turn on the opto when i need the 240Vac and turn off when i dun need it? (refering to the circuit shown by u)
thanks alot
