2N3904 PDF Datasheet

The 2N3904 is NPN switching transistor.

The 2N3904 is a widely used bipolar junction transistor (BJT) that is commonly used in electronic circuits. It is an NPN transistor with a maximum current rating of 200 mA and a maximum voltage rating of 40V. The 2N3904 is known for its low noise and high gain, making it suitable for amplification applications.


1. Low noise
2. High gain
3. Widely available
4. Relatively inexpensive
5. Suitable for amplification applications


1. Limited maximum current and voltage ratings
2. May not be suitable for high-power applications
3. May require additional circuitry for stability and biasing

It also consolidates and displays results from multiple manufacturers with the same part number and similar functionality.


Searched parts can be used interchangeably as substitutes for one another, But it's important to note that the parameters for each manufacturer may vary slightly.
