2N2222 Pinout Diagram
The 2N2222 transistor is a widely used NPN bipolar junction transistor (BJT) with three main terminals: the emitter, base, and collector. Here is a brief summary of each terminal’s function:
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | Emitter | The emitter pin, where current flows out of the transistor. This is typically connected to the ground or negative side of the circuit. |
| 2 | Base | The base pin, which controls the current flow between the collector and emitter. A small current at this pin allows current to flow between the other two pins. |
| 3 | Collector | The collector pin, where current flows into the transistor. It is connected to the load in most circuits. |
The 2N2222 transistor’s three pins – emitter, base, and collector – are fundamental to its operation. Proper understanding and connection of these pins are crucial for effective use in both switching and amplification tasks within various electronic projects.
