BD649 NPN Darlington power 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.
