Popular Hobbyist Transistor Types

Hi All.

There are certain junction transistor type numbers that are popular with hobbyists and the industry in general. ie: these very popular and inexpensive:

2N3904 NPN 40V
2N3906 PNP 40V
2N4401 NPN 40V higher current
2N3055 NPN power, low quality, old tech, low frequency
2N2955 PNP power, low............................................
2N3773 NPN good quality power >100V
TIP31C, TIP41C, TIP42C TO-220 case NPN and PNP power, bulletproof

I would like to know what popular small signal transistor types are commonly used at 60V, 80V and 100V for greater and less than 100mA, preferably in TO-92 or similar plastic packages?
For you guys in Europe, what types do you use? BCXX types? I am not familiar with the European or UK popular type numbers.

Thanks

I like the BC548 because it's high gain and the saturation voltage is specified with a forced beta of 20 which is useful for driving large loads with low base currents.

The BC338 is also good for a similar reason, the beta is 60 with a collector current of 300mA and a collector emitter voltage of 1V and will saturate pretty well at higher currents with a forced beta of 30.

Bump!

Thanks Hero!

Anyone else? Or should I just go to the Maplin web site to see what Brits, French, Dutch and Germans are using?

BTW, anywhere else besides Maplin?

[Edit] Maplin doesn't have much at all, and no high freq PNP, no Pch JFET..........

There are lots of other suppliers: RS Components, Farnell and Rapid Electronics are the most common ones over here.
 
Digi-Key too. Just small talk: Last time I emailed 'em about magnetic compass sensors KMZ51 and they replied that they don't sell 'em anymore. I'm so disappointed. That's the end of KMZ51.

Hehee. :D
