FWIW, the number "307AAP3" at usbid.com brings up Fairchild as the
manufacturer. "9622" is probably a YYWW date code.

I went to Mouser and searched 307AAP3 and got nothing.
On QTC I got mostly these guys,
http://www.mouser.com/phoenix .
One piece that came up was
http://www.mouser.com/fairchildsemi ,
and this was an opto device, but a sensor only.
Being a through hole device probably puts it at '96 or older, since
surface mount has taken over, so at 12 years this may be a junk/surplus
part and not even on any major site. Get some 20 year old data books and
you might find it.
Good luck,

I now believe that QTC is Quaestus Corporation, an optocoupler supplier
which was acquired by Fairchild and then sold to Everlight.
