WebThe 2N2222 is a type of bipolar junction transistor (BJT) that is commonly used as a small-signal NPN transistor. It was one of the first transistors that were widely used, and it is still used today in a wide range of applications. The 2N2222 is known for its reliability and ease of use. The 2N2222 transistor has three regions: the emitter ... WebMar 26, 2016 · One of the first transistors to be invented was the bipolar junction transistor (BJT), and BJTs are what most hobbyists use in home-brewed circuits. BJTs consist of two pn-junctions fused together to form a three-layer sandwich-like structure. A pn-junction is the boundary between two different types of semiconductors: a P-type semiconductor ...
