HISTORIC TRANSISTOR HOBBYIST SUPPLIES!
Supplies for the Transistor Historian and Kit Builder.
Only from the TransistorMuseum™
In 1954, Texas Instruments announced the commercial
availability of silicon grown junction transistors. This was an industry first and marked
the beginning of TI’s rapid expansion as a semiconductor giant. These initial silicon transistors were
very crude, almost handmade grown junction devices, and were labeled as
types 903, 904, 905 and X15. TI
sold large quantities of these early silicon transistors at high prices to
the military, taking advantage of the superior operating temperature range
of silicon compared to germanium. Early devices sold for over $100
each! TI sold this historic
product line (with updated part numbers) well into the 1970s. Beginning
in the late 1950s, several of the 900 series devices were relabeled with
the standard JEDEC “2N” sequence, so that the 903 was updated as the 2N1149
and the 904 became the 2N1150. Due
to the popularity and widespread use of these early silicon transistors, several
of the types were manufactured by “second source” suppliers. For example, in
the mid 1960s, National Semiconductor developed and sold the 2N1150 (in a
black plastic case).
