Typical early 1960s Transitron 2N343
transistors were marked as shown above -
the “6123” date code denotes 1961 week 23.
Additional 2N343 Historical Information: Texas Instruments
introduced the 2N339 – 2N343 line of medium power silicon
grown junction transistors in 1957. This is a very early
timeframe for silicon technology, as only three years had
passed since the introduction of the first commercial silicon
transistors by TI in 1954. During the 1950s, transistor
technology was advancing rapidly, and the grown junction
technology used for these first silicon transistors was soon
superseded by more advanced technologies such as
diffused/mesa and planar. The line of related devices
numbered from 2N339 through 2N343 differed primarily in
breakdown voltage and gain, and the 2N343 was the highest
performing type. The military was a major user of these early
silicon transistors, and prices were quite high as the demand for
this new technology was expanding rapidly. For example, the
1960 Lafayette Radio catalog lists the 2N343 from TI for $30.
That’s over $200 in 2012 prices. With this type of financial
incentive, other companies soon began competing with TI.
Transitron was the major second source supplier for the 2N339
– 2N343 line of transistors, and sold millions of these devices
into the 1960s. Although most applications for the 2N343 were
military related, this device could also be used in
commercial/hobbyist audio circuits. Shown at right is a
unique audio amplifier originally shown in the High Fidelity
section of the 1962 Sixth Edition of the GE Transistor Manual.
The 2N2107 transistor in the circuit is equivalent to the 2N343.
Historical Background: Several companies were leaders in
producing the first types of silicon transistors in the 1950s.
Shown above is a section of the 1960 Transitron catalogue,
with the claim “Industry’s broadest line of silicon transistors.”
Note the variety of case styles, from small low power devices,
to the medium power 2N343 type (upper right in illustration),
to the high power types with heavy metal cases (lower right).
The 2N343 was listed as a general purpose One Watt device,
designed for low level signal applications, including audio or
servo amplifiers, and was qualified for military
