BC556 … BC559
PNP Silicon Epitaxial Planar Transistor
for switching and AF amplifier applications.
These transistors are subdivided into three groups A, B
and C according to their current gain. the type BC556
is available in groups A and B, however, the types
BC557 and BC558 can be supplied in all three groups.
The BC559 is a low-noise type available in all three
groups. As complementary types, the NPN transistors
BC546…BC549 are recommended.
On special request, these transistors
manufactured in different pin configurations.
