2N2222A-M pdf datasheet transistor


2N2222A-M is NPN TRANSISTOR. This indicates the maximum collector-emitter voltage the transistor can withstand without breakdown. In this case, it is 40 volts. This specifies the maximum collector current the transistor can handle without getting damaged. Here, it is 800 milliamperes or 0.8 amperes.

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.
