NPN Silicon Epitaxial Planar Transistors

These transistors are subdivided into three groups

A, B and C according to their current gain. The type

BC546 is available in groups A and B, how-

ever, the types BC547 and BC548 can be

supplied in all three groups. The BC549 is a

low-noise type and available in groups B and

C. As complementary types, the PNP transis-

tors BC556 … BC559 are recommended.

On special request, these transistors are also

manufactured in the pin configuration TO-18.
