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

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..
