Title: info on 2SB186 or 2SD72 Transitors?
Post by: Leftrights on February 15, 2004, 10:34:33 PM
Does anyone have any data sheets, anicdotal information or folk tales for 2SB186 transitors?  Or 2sd72's?  I came across a few and I con't get my transitor checker working...

Any info would really help alot.

Vcbo (V) -25
Ic (ma) -150
Pc (mw) 200
Icbo (ua) - 15
Vcb (V) -20
hfe 120

2SD72
Vcbo (V) 25
Ic (ma) 600
Pc (mw) 720

Thanks Mark!  That's awsome.  You are an inexuastable fountain of knowledge.  There was nothing online.  I take it you got that from your all inclusive data sheet book that you mentioned in another thread.  Would I ever love to have one of those.  You should copy it and sell it on ebay...

Anyway's thanks again :D

There are two reasons why I would not do that.  One is that I don't charge for information (the primary reason why I'd go broke as a consultant, even though I know more than most of the ones I run into).  The other is that it is a scan of a book which is commercially available.  I'm not sure how it was scanned in the first place.  All I know is that I have a scan, it's bloody huge, it's entirely in graphics format (though bookmarked), and I owe a debt of gratitude to the gentleman who provided it to me (which I partly repay by not distributing it and getting him in trouble).

You and other folks can always ask, though, and as long as I have the time I'll answer.  I may even learn something about transistors along the way.
