Package

The MMBT3904T is typically packaged in a SOT-23 surface-mount package. This compact package allows for efficient use of PCB space and is suitable for a variety of electronic applications.

Pinout

The MMBT3904T is a NPN bipolar junction transistor (BJT) typically used for general purpose switching and amplification applications. It has a total of three pins. The pin configuration is as follows:
1. Collector (C) - This is the terminal where the output is taken. It is connected to the load and receives the current.
2. Base (B) - This terminal controls the transistor's operation. A small current at the base allows a larger current to flow from the collector to the emitter.
3. Emitter (E) - This is the terminal through which current exits the transistor. It acts as the reference point for the collector current.
In summary, the MMBT3904T features a 3-pin configuration (C, B, E) that facilitates its function in electronic circuits for amplification and switching tasks.
