|Germanium Alloy Transistor - 1956
TI number: G00203
These transistors were built in 1956 and represent one of the early designs.
The package design was a TI predecessor to the standard JEDEC TO-11. The header was gold plated for corrosion resistance, and the package was painted black to provide corrosion resistance for the can plus increased heat dissipation. In the symbolization, "980" was the Federal Stock Code for TI; "639" was the manufacturing date code for 1956, 39th week. See G00202 for internal construction.
