In an NPN transistor, the connection between base and collector is a PN junction, so as you might expect it shares its properties with the PN junction in a diode.

There is a third transistor amplifier configuration, as you might expect for a device that has three terminals: ... Assuming the NPN is the input, its emitter will sit about 0.6V below its base.

There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

An NPN transistor is an electronic component used as a switch or amplifier. It has three legs: base (B), collector ©, and emitter (E). In circuit diagrams, the base is usually in the middle, the ...
