Npn Transistor Schematic Diagram. Npn transistors are used in the applications where there is a need to sink a current. What is a npn transistor.
Npn transistor switching circuit. Below are a few example circuits. These back to back pn junction diodes are known as.
Used in the darlington pair circuits to amplify weak signals.
The npn transistor behaves like two pn junctions diodes connected back to back. Its pin configuration diagram is shown here according to datasheet. Let s look at the most fundamental transistor switch circuit. The collector is always connected to the positive supply and the base is in negative supply for controlling the on off states of the transistor.
