Features
鈥?NPN Silicon Epitaxial Planar Transistors
鈥?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,
however, 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 transistors
BC556...BC559 are recommended.
鈥?On special request, these transistors are also
manufactured in the pin configuration TO-18.
