Use 4N25, 4N35, TIL111. In this application no need nothing special.(i think the designer found this in trash...)

i was not able to find the TIL111, but i found the other two. they work the exact same? (in this application anyway...)

what does an optocoupler do?

Sebi · 7th April 2004, 06:58 PM

David,

The optocoupler contains one (or two) IR LED as input, and (e.g. in 4N25) phototransistor as output. But existiert with different semiconductors as output: MOC3021 optotriac, MOC3041 optotriac with zerocross switch,analog switch, MOSFET. The big advantage: galvanic isolation up to 2....6kV.

Anyway, in this application work fine the 4N25..
