DESCRIPTION
The BDX53B and BDX53C are silicon
Epitaxial-Base NPN power transistors in
monolithic Darlington configuration mounted in
Jedec TO-220 plastic package. They are intented
for use in hammer drivers, audio amplifiers and
other medium power linear and switching
applications.
The complementary PNP types are BDX54B and
BDX54C respectively.
