The BDX33B is silicon Epitaxial-Base NPN power transistors in monolithic Darlington configuration mounted in Jedec TO-220 plastic package. They are intended for use in power linear and switching applications. The complementary PNP types is BDX34Brespectively.
What is Darlington Transistor?
A Darlington transistor is also known as a Darlington pair is an electronics component made via the combination of two PNP or NPN BJTs (Bipolar Junction Transistor) connected in such a way that it allows a very high amount of current gain. Darlington pair is simply used in many applications where switching or amplification is crucial.
