NPN Silicon Epitaxial Planar Transistors
for switching, AF driver and amplifier
applications.
Especially suited for automatic insertion
in thick- and thin-film circuits.
These transistors are subdivided into three groups -16,
-25 and -40 according to their current gain.
As complementary types, the PNP transistors BC807
and BC808 are recommended.
