 Others - i could not find specs for. Will notify later, if found.

Marco,


2N... means American transistors, BC... are European transistors.

American designation:

1N.... is used for semiconductors with 1 junction like a diode i.e.
1N4148,
2N.... is used or semiconductors with 2 junctions like a transistor i.e.
2N2222,
3N... for other semiconductors like smal IC* like optocopler i.e. 3N435,

You have also exeptions!

European designation:

I cannot give you all the details because you have a lot of different
letters used.

The first letter:

A = Ge material semiconductors,
B = Si material semiconductors,
C = GaAs material semiconductors,
R = Compound material.

The second letter:(the most popular ones):

A = Diode (low power, signal);
B = Diode (variable capacitance));
C = Transistor (low power, audio frequency);
D = Transistor (power, audio frequency);
F = Transistor (low power, high frequency);
L = Transistor (power, high frequency);
R= control and swithching device);
S = Transistor (low power, swithching);
T = thyristors;
U = Transistor (power, switching);
X = Diode (varactor, multiplier);
Y = Diode (rectifier);
Z = Diode (zener).

You have also sometimes a tirth lertter, see a Philips data books for
more details.

In you case: 2N means you have an American transistor, and BC is an
European Si, low power, LF transistor.

The Japanese designation:

2SB, 2SC, 2SD*, for transistors but it is difficult to get informations
about Japanese semiconductors!

Hope this can help you.

Regards.

2N types are fets, bipolars, thyristors, triacs and other semiconductors
with three active connections registered at JEDEC and perhaps other
U.S.A.
institutes. There is also a 3N series, I think they are all dual gate
fets.
BC are small power low frequency silicon transistors registered at Pro
Electron, a european institute.
Often the same transistor is sold in North America with a JEDEC code,
and in
Europe with a Pro Electron code.
Philips supplies many 2N types, and Motorola has many BC types.

The pro electron code is generally more systematic than the JEDEC code.
Philips databooks (discrete semiconductors series) often explain the Pro
Electron code and the meaning of the first, second and sometimes third
letter.

A web site that explains not only the JEDEC and Pro-Electron code, but
also
the japanese JIS code is:

Any company not member of one of those designations may and will override
these specifications. Especially with modern things like digital
Transistors...

*** PRO-ELECTRON-designation (Europe): ***

A) Used in Radio-/TV-/Tape- units : AAxxx (2 letters, 3 digits)
B) Used in commercial units : AAAxx (3 letters, 2 digits)
(don't ask what the diff. between a commercial and a TV is...)

FIRST LETTER
A = Germanium
B = Silocon

SECOND LETTER

C = Transistor, low Power, low frequency (audible sepctrum)
D = Transistor, high power, low frequency (audible sepctrum)
F = Transistor, low power, high frequency (antennas, HF, Tuner,radar)
L = Transistor, high power, high frequency
S = Transistor, low power, Switch applications
U = Transistor, high power, Switch applications (BU208, TV defl.
Transistor)

SUFFIX
A =low signal amplification (BC-548A)
B = medium signal amplification (BC-548B)
C = high signal amplification (BC-548C)

*** JEDEC-designation (America): ***

2N for 2-junctions
3N for more. Like ICs, Optos,...

*** JIS-designation (Japan): ***

2SA... or 2SB   PNP-Transistor
2SC... or 2SD*   NPN-Transistor
