PNP Silicon Epitaxial Planar Transistors

for switching and AF amplifier applications.

Especially suited for automatic insertion in

thick- and thin-film circuits.

These transistors are subdivided into three groups A, B

and C according to their current gain. The type BC856 is

available in groups A and B, however, the types BC857,

BC858 and BC859 can be supplied in all three groups.

The BC859 is a low noise type.

As complementary types, the NPN transistors

BC846 … BC849 are recommended.
