Features
■ Products are pre-selected in DC current gain Application
■ General purpose
3 Description 1 SOT-32 These epitaxial planar transistors are mounted in
the SOT-32 plastic package. They are designed
for audio amplifiers and drivers utilizing
complementary or quasi-complementary circuits.
The NPN types are the BD135 and BD139, and
the complementary PNP types are the BD136
and BD140. Figure 1.
