FEATURES
♦
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 available in groups A and B, however, the types
BC557 and BC558 can be supplied in all three
groups. Th e BC559 is a low-noise type availa ble
in all three groups. As complementary types, the
NPN transistors BC546 … BC549 are recomme nded.
♦
On speci al request, these tran sistors ar e also ma nufactured in the pin configuration TO-18.
