|Silicon Grown Junction Transistor
TI number: G00007
Typical of original TI silicon grown junction transistor. The first commercially available silicon transistor was announced by TI in May, 1954. The first type numbers were TI901 & TI902.
Can is soldered to header for hermetic seal. Production of this design continued until 1962. Gordon Bellah found that TI requalified a design change for the USN 2N117 series with a narrow weld flange in March, 1961. Memory, verified by check with Howard Moss, was that this change permitted ending production of the soldered can by late 1961 or early 1962 without causing a customer assembly problem.
