TRANSISTORS: Soviet Transistor Pinouts

 Just a little reference to Soviet-era transistor pinouts.   

SOVIET TRANSISTOR PINOUTS

note:  in addition to potentially different pinouts, some Soviet-era transistors can have the case connected to the base - which is not good if it touches anything else.  The dot on the case usually marks the emitter, not the collector as often found on European transistors 

Common Transistor Pinouts & Numbering Systems

COMMON SILICON TRANSISTOR PINOUTS

TRANSISTOR NUMBERING SYSTEMS

JEDEC (JOINT ELECTRON DEVICE ENGINEERING COUNCIL)

example:  2N2222

First Number

1 = Diode

2 = Bipolar transistor or single gate field effect transistor

3 = Dual gate field effect transistor

Second Letter

= N 

Subsequent numerals

= Serial number

Important to note that there is no correlation between the number assigned and the type or properties of a transistor.  Numbers are assigned in order of registration.

----------------------------------------------------------

JIS (JAPANESE INDUSTRIAL STANDARD)

example:  2SC828

First Number

1 = Diode

2 = Bipolar transistor or single gate field effect transistor

3 = Dual gate field effect transistor

Second and Third Letters

SA:    PNP HF transistor

SB:    PNP AF transistor

SC:    NPN HF transistor 


SD:    NPN AF transistor

SE:    Diodes

SF:    Thyristors

SG:    Gunn devices

SH:    UJT

SJ:    P-channel FET/MOSFET 

SK:    N-channel FET/MOSFET

SM:    Triac

SQ:    LED

SR:    Rectifier 

SS:    Signal diodes

ST:    Avalanche diodes 

SV:    Varicaps

SZ:    Zener diodes

 

Subsequent Numerals

The serial number follows the first digit and the two semiconductor device type letters. The numbers run between 10 and 9999.

------------------------------------------------------

PRO-ELECTRON / EECA (EUROPEAN ELECTRONIC COMPONENT MANUFACTURERS ASSOCIATION)

example:  BC549C

First Letter

The first letter indicates the material.

A = Germanium

B = Silicon

C = GaAs

R = Compound materials

Second Letter

The second letter indicates the device application.

A:    Diode RF 

B:    Variac

C:    Transistor, AF, small signal

D:    Transistor, AF, power

E:    Tunnel diode

F:    Transistor, HF, small signal

K:    Hall effect device

L:    Transistor, HF, power

N:    Optocoupler

P:    Radiation sensitive device

Q:    Radiation producing device

R:    Thyristor, Low power

T:     Thyristor, Power

U:    Transistor, power, switching

Y:    Rectifier

Subsequent Characters

The serial number of the device. 

• domestic use has three numbers

• commercial or industrial use has a letter followed by two numbers, i.e. A10 - Z99.

Suffix

A = low gain

B = medium gain

C = high gain

MANUFACTURERS OWN SCHEME

NOTE:  Some manufacturers will follow their own numbering schemes

example:  MPSA by Motorola, and a lot of old germaniums, NKT etc, but that's another topic entirely

MILITARY SPEC

There are several different codes between the UK, NATO, the US, and of course, the Soviet Union.  I will not attempt to list them all here. 

CV:      UK

Usually CV followed by 4 numbers - no relation to the original part number.

JAN:    USA

JAN is a prefix ahead of normal JEDEC code
