Transitron 2N342

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 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. 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.
