BDX33B BDX33C
COMPLEMENTARY SILICON POWER
DESCRIPTION
The BDX33B and BDX33C are silicon
Epitaxial-Base NPN power transistors in
monolithic Darlington configuration mounted in
Jedec TO-220 plasticpackage. They are intented
for use in power linear and switching applications.
The complementary PNP types are BDX34Band
BDX34Crespectively.
