This is 40V, 0.6A, Silicon Planar Epitaxial NPN Transistor. 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.
The 2N2219A and 2N2222A are silicon Planar Epitaxial NPN transistors in Jedec TO-39 (for
2N2219A) and in Jedec TO-18 (for 2N2222A) metal case. They are designed for high speed
switching application at collector current up to 500mA, and feature useful current gain over a
wide range of collector current, low leakage currents and low saturation voltage […]
