Description
Q2N2222 is NPN Silicon Amplifier Transistor. This transistor is a commonly used NPN bipolar junction transistor (BJT) in electronic circuits. It is a small-signal transistor with versatile applications and is widely available in the electronics industry.
A NPN transistor is a type of bipolar junction transistor (BJT) that consists of two n-type semiconductor materials separated by a single p-type material.
The NPN transistor is used to amplify or switch electronic signals and is widely used in many electronic circuits. It works by controlling the current flow between the collector and emitter terminals through the base terminal.
When a small current is applied to the base, it controls a much larger current between the collector and emitter, making the NPN transistor an effective amplifier or switch.
