I have seen some pictures of the internals of the 2n3055 transistors
from China and some had a very small silicon area compaired to the

to 1 amp.


** 2N305s have been around since the mid 1960s and undergone number of chip redesigns in that time.

The JADEC specification does not determine the chip itself - only its overall performance. Long as the watts, volts amps, gain and Ft etc are OK you can label it as a 2N3055.


The term is JEDEC. Can't you get anything right?
