info on 2SB186 or 2SD72 Transitors?

[Leftrights]

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.

Here's what I have these in my Japanese transistor manual.

2SB186:
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
Icbo (ua) 50
Vcb (V) 20
hfe 150

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

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.
