Japanese diode numbering starts with 1S as US ones start with 1N,  but 1S6 
sounds like it's awfully short -- could there be more to it?

I've had good luck lately with www.alldatasheet.com which lets you put in part 
of a part number and it'll list everything that matches.  Give that a shot.  
The usual search engines haven't done me real well when it comes to finding 
data on parts,  most of the time.
