AC switch

Dec 06, 2003 4 Replies

I'm looking for an opto-isolated input triac that can do about 1-2 amps. I have found some that are in the milliamp range intended for driving small loads or the gates of larger triacs, but nothing such as a 4 termimal device in the 1-2 amp range, 24VAC. Any help?


found some

larger triacs,

You either need to buy a "solid state relay" module or build your own with a

6-pin opto-isolated TRIAC driving a larger 3-terminal device, plus a few R's and C's for snubbing. The second option is usually much cheaper, and it is not too hard to do, but the SSR modules come with a nice UL sticker already on them.

Thanks to all for suggestions. It looks like Sharp has the best selection in the 1-2 amp single package. They have 1.2 amp in an 8-DIP, which is perfect for the application.
