Features
鈥?PNP Silicon Epitaxial Planar Transistors for switch-
ing and AF amplifier applications.
鈥?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. As complementary
types, the NPN transistors BC546...BC548 are
recommended.
鈥?On special request, these transistors are also
manufactured in the pin configuration TO-18.
