4. Power Dissipation: Maximum power dissipation of about 625mW.
5. Gain: High current gain (hFE) typically ranges from 100 to 300, providing efficient signal amplification.
6. Frequency Response: Transition frequency (fT) up to 250MHz, enabling high-frequency operation.
7. Package Type: Available in a variety of packages, commonly in SOT-23 and TO-92 for versatile application use.
8. Applications: Suitable for switching and amplification in audio, RF, and digital circuits.
These features make the PMBT3904 ideal for a wide range of electronic applications, including signal processing and low-power switching tasks.

Package

The PMBT3904 is commonly available in a surface-mount package type, specifically the SOT-23. This compact package is designed for efficient space utilization in electronic circuits.

Pinout

The PMBT3904 is a general-purpose NPN bipolar junction transistor (BJT) commonly used for switching and amplification applications. It comes in a TO-92 package and has three pins with the following functions:
1. Collector (C): The terminal where the output current flows out. It is connected to the load in switching applications.
2. Base (B): The control terminal that regulates the current flow between the collector and emitter. A small current at the base allows a larger current to flow from collector to emitter.
3. Emitter (E): The terminal where the output current flows in. It is usually connected to ground in common-emitter configurations.
The pin configuration (looking at the flat side of the TO-92 package) is: Emitter (left), Base (middle), Collector (right).
