A SURVEY OF EARLY POWER TRANSISTORS by Joe A. Knight TRANSITRON 1950s/60s GERMANIUM AND SILICON POWER TRANSISTORS |

The Transitron Electronic Corporation (hereafter referred to as ‘Transitron'), began as a small venture firm in 1952 and found their early success in making mil-spec higher voltage 'gold-bonded' diodes. No doubt having secured the Western Electric transistor license they started into the semiconductor market sometime in 1953. By late 1954 Transitron had secured cross-licensing approval with several larger manufacturers and was producing the more common junction types: the 2N34 (RCA), the 2N43 (GE) and the 2N65 (Ray.). One of the keys to Transitron's early product expansion was a sizable investment in R&D, including a large staff of scientists and engineers. Their successful work on silicon diodes and rectifiers well prepared the company to move into silicon transistor manufacturing, following close behind T.I. in this field.

As can be seen from this January, 1955 ad (see at left), Transitron had already developed many transistors and diodes for several areas of application, including medium and high power output devices. This was quite a formidable transistor line-up for having only been in business less than three years.
