Silicon Grown Junction Transistor - 1957
TI number: G00049

Example of 1957 period engineering study. A shorter silicon bar had the collector and emitter ends mounted on kovar tabs which were welded to the header posts.

Item was part of the original S/B Lobby display. Advantages were lower saturation resistance and better heat dissipation. Method was not used for production because the advantages for normal use did not justify the higher product-costs.
