YES ! as a beginner myself, I study all day long, and then, when I
think I know the Ebers-Moll transistor model and I need one
with characteristic xyz, it all boils down to
"What is the right choice for this ?".
and the answer is "99% of all cases just use the bog-standard BC547"
(or 2n2222, or whatever)
I would very much like a list of "normal", a bit up-to-date, and above all obtainable suggestions, for
transistors, power transistors, jfet, enhancement fet, power mosfet,
signal diode, protection diode, audio range op-amp, high freq op-amp,
comparator, and maybe a few often occurring digital chips...
maybe you can put your list in the playground, and we can all enhance it.
Thx !
