PNP Silicon Epitaxial Planar Transistors 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 avail-

able 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 are also manufac-

tured in the pin configuration TO-18.
