DESCRIPTION
The BD135, BD137 and BD139 are silicon
epitaxial planar NPN transistors in Jedec SOT-32
plastic package, designed for audio amplifiers
and drivers utilizing complementary or quasi
compementary circuits.
The complementary PNP types are the BD136                                             1
BD138 and BD140.                                                                  2
