BC856 to BC859
Vishay Semiconductors
Small Signal Transistors (PNP)
Features
鈥?PNP Silicon Epitaxial Planar Transistors for
switching and AF amplifier applications.
鈥?Especially suited for automatic insertion in thick
and thin-film circuits.
鈥?These transistors are subdivided into three groups
A, B, and C) according to their current gain. The
type BC856 is available in groups A and B, how-
ever, the types
BC857, BC558 and BC859 can be supplied in all
three groups. The BC849 is a low noise type.
鈥?As complementary types, the NPN transistors
BC846...BC849 are recomended.
