Subject: [TN] Identifying ST Microelectronics Diode

Hi All!
 
Hope you all had a good Independence Day! Mine was great! Sat back and
enjoyed the time off from work, and appreciated all the sacrifice and effort
that was made by the generations before me so that I could enjoy what I have
today. 
 
Anyway, there's this maintenance guy where I work who is just awesome when
it comes to fixing things, but he has run into something that he's having
trouble with. The generator in his truck came apart, and he's been able to
get everything back together except for a couple of diodes that are inside.
They are both the same and I have a couple of pictures of it:

You can see that it is an axial diode, and appears to be a
STMicroelectronics diode. I tried to show the markings that are on it, which
are:
 
C9245
BY628S
 
I don't know what this really is. I've searched, and searched and can't find
anything that ties into the numbers that's marked on the diode. Forget about
calling STMicroelectronics, you'll get routed to somebody's voicemail to
leave a message that will never be returned. Does anybody know what diode
this is?
 
I might be able to save my maintenance guy around $600 if I can find him
replacement diodes for his truck generator. He won't have to buy a new
generator then...
 
Steve
