NPN Transistor Question

Started by Jim Thompson June 5, 2015
Being in the I/C biz, I don't keep up very well with what is available
in the discrete transistor world.

What I'm looking for is a _readily_available_ NPN, highest fT, 
VCE < 15V, IC < 10mA

Suggestions?

Thanks!

I love to cook with wine.     Sometimes I even put it in the food.

That practically oscillates just laying on the table! -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com
They're really amazing at low current, though.  
High Early voltage, good beta ar low current.
