Bjt Pin Diagram. The 2n2222 is considered a very common transistor and is used as an exemplar. Bipolar junction transistor amplifier.
A bipolar junction transistor bjt is a type of transistor that uses both electrons and electron holes as charge carriers in contrast a unipolar transistor such as a field effect transistor uses only one kind of charge carrier a bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between two other terminals making the device. It is designed for low to medium current low power medium voltage and can operate at moderately high speeds it was originally made in the to 18 metal can as shown in the picture. The maximum amount of current.
The 2n2222 is a common npn bipolar junction transistor bjt used for general purpose low power amplifying or switching applications.
Although this question is essentially nothing more than an exercise in algebraic manipulation it is also a good lead in to a discussion on the importance of power dissipation as a semiconductor device rating. Although this question is essentially nothing more than an exercise in algebraic manipulation it is also a good lead in to a discussion on the importance of power dissipation as a semiconductor device rating. 2n2222a is a npn transistor hence the collector and emitter will be left open reverse biased when the base pin is held at ground and will be closed forward biased when a signal is provided to base pin. A standard bjt s pin out includes collector emitter base and a standard mosfet pin out includes gate drain and source.
