BD647 NPN Darlington Transistor – Datasheet

BD647 NPN Darlington transistor is Lot of variations for robust device performance and reliable operation application designed for use as complementary AF push-pull output stage applications.

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.
