The TO-92 transistor package is marked
C1815GR
PH 3 9
From my past experience I surmise that it's a 2SC1815 from Philips,
right? Also, I surmise that this is a Japanese transistor number.
Anyway I google for 2SC1815 and of course nothing having to do with
data sheets comes up, just thousands of companies wanting to sell
them.
Somehow I get the idea that the 2SC1815 is made by Toshiba so I go to
their website and go thru menues and click on 'view details' but
nothing happens. I look at the bottom of the screen and it says
something about javascript so I figured that Mozilla wasn't going to
run that, so I changed to IE 6 and it ran, and I could view and save
their data sheet for 2SC1815, in Adobe Acrobat Reader .PDF.
But I'm pretty sure this is a Philips transistor so I go to their
website and search for 2SC1815 and it says "No search results could be
found using the given input."
So I go all sorts of these product selection menues, and finally come
to a couple hundred transistors. All I can find is 2PC1815 so I click
on that but nothing happened. So I go back to the screen with a
search fill-in and I search for 2PC1815 and _finally_ I get a data
sheet for the transistor. I compared the specs with those from the
Toshiba data sheet, and the 2PC1815 is Philips' version of the
2SC1815. But Philips' data sheet gives no graphs, just text
information.
So I go back to the Toshiba data sheet and find from their graphs that
the Ft of 80 MHz isn't typical, it's a minimum, and the actual typical
Ft is more like 200 to 300 MHz at typical I and V. Which was really
what I wanted to know all along.
I feel like I could pull a rabbit out of a hat after all that zigging
and zagging.
Philips motto is "Let's Make things better." Yeah, right. More like
substitute worse for better.
