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 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.

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backwa… ...

NPN transistors are key components in electronics, used as switches or amplifiers with three legs: base, collector, and emitter. Thyristors are semiconductor switches with three legs: gate, anode ...

The voltage on the emitter of the PNP transistor in this oscillator circuit is a good sawtooth (but do not load it much as it is at a high impedance). Also, the current out at the emitter of the NPN ...

This Design Idea presents anunusual method of performing theexclusive functions with two resistors,four diodes, and one transistor.The NPN configuration results inthe XNOR operation, and the ...
