To obtain these curves, a high−gain and a low−gain unit were selected from the 2N4401 lines, and the same units were used to develop the correspondingly numbered curves on each graph. Figure 11.

Jan 10, 2007 · For what it's worth, the background to that family of transistors goes something like this: the "BC" at the start identifies a silicon audio transistor (using the Pro-electron naming scheme, which I think is more helpful than JEDEC), and is reasonably easy to find explained on the internet, but there isn't exactly a formal system to the number ...

The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz. These were made by etching depressions into an N-type germanium base from both sides with jets of Indium(III) sulfate until it was a few ten-thousandths of an inch thick.
