The BDX34B silicon Epitaxial-Base PNP power transistors in monolithic Darlington configuration mounted in Jedec TO-220 plastic package. They are intented for use in power linear and switching applications. The complementary PNP type is BDX34C respectively.
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.
