Pinout

The 2N3906 is a PNP bipolar junction transistor (BJT) commonly used for amplification and switching applications. It has a total of three pins, each serving a specific function:
1. Emitter (E) - The terminal through which the charge carriers (holes for PNP) leave the transistor. It is typically connected to a higher voltage in a PNP configuration.
2. Base (B) - The terminal that controls the transistor's operation. A small current at the base allows a larger current to flow between the emitter and collector, enabling amplification.
3. Collector (C) - The terminal through which the charge carriers enter the transistor. The collector is typically connected to a load.
The standard pin configuration is as follows when looking at the flat side of the transistor:
1. Emitter (E)
2. Base (B)
3. Collector (C)
The 2N3906 is widely used due to its versatile performance and availability.
