BC846 THRU BC849
Small Signal Transistors (NPN)
FEATURES
♦ NPN Silicon Epitaxial Planar Transistors

SOT-23
.122 (3.1)
.118 (3.0)
.016 (0.4)

.056 (1.43)
.052 (1.33)

♦ 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.
