60 years of popular transistors
In the ever-dynamic and fast-moving world of semiconductors, why do some old transistors like 2N3904 and BC547 keep on going for decades? The 2N3904 and BC 547 transistor is still available as a newly manufactured device after 60 years of their introduction. The construction of the 2N3904 and 2N3906 in the mid.1960s represented a significant →
