• NPN Silicon Epitaxial Planar Transistors for switching
and AF amplifier applications.
• Especially suited for automatic insertion in thick and
thin-film circuits.
• These transistors are subdivided into three groups (A, B,
and C) according to their current gain. The type BC846 is
available in groups A and B, however, the types BC847 and
BC848 can be supplied in all three groups. The BC849 is a
low noise type available in groups B and C. As complementary
types, the PNP transistors BC856...BC859 are recommended.
