Description

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.
