NPN BDX33 – BDX33A – BDX33B – BDX33C
PNP BDX34 – BDX34A – BDX34B – BDX34C
COMPLEMENTARY SILICON POWER
DARLINGTON TRANSISTORS
The BDX33B, BDX33B and BDX33C are silicon epitaxial-base NPN power
transistors in monolithic Darlington configuration and are mounted in Jedec TO-
220 plastic package.
They are intented for use in power linear and switching applications.
The complementary PNP types are the BDX34A, BDX34B and BDX34C
respectively.
