2N2222 Pinout
2N2222 Pinout
The 2N2222 is a widely used NPN bipolar junction transistor (BJT). It is commonly employed in switching and amplification applications in various electronic circuits. Understanding its pinout is essential for proper integration into your designs. Below is a summary of the 2N2222 transistor’s pinout and their functions:
ピン | 名前 | 説明 |
---|---|---|
1 | エミッター | The Emitter is the reference point for current flowing out of the transistor. It is usually connected to the negative side of the circuit. |
2 | ベース | The Base controls the transistor’s switching. A small current into the Base allows current to flow from Collector to Emitter. |
3 | コレクタ | The Collector is the terminal where the current flows into the transistor. It is connected to the positive side of the circuit. |
By understanding the 2N2222 pinout and how each terminal functions, you can effectively utilize this versatile transistor in your projects for a variety of applications.
