FEATURES
♦
PNP Silicon Epitaxial Planar Transistors
for switching and AF amplifier appl i cat ions.
Especially suited for automatic insertion in
♦
thick- and th i n - film circuits.
♦
These transistors are subdivided into three groups A, B
and C according to thei r current gain. The type BC856 i s
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 transis tors
♦
BC846…BC849 are recommended.
