Pinout

The BC547B is a NPN bipolar junction transistor (BJT) commonly used for general-purpose amplification and switching applications. It has three pins:
1. Collector (C) - This is the terminal through which the primary output current flows. It collects electrons from the emitter and allows current to flow to the load.

2. Base (B) - The base terminal controls the transistor's operation. A small current applied to the base allows a larger current to flow from the collector to the emitter, enabling amplification or switching.
3. Emitter (E) - The emitter terminal is where the charge carriers (electrons, in the case of NPN) leave the transistor. It is connected to the common ground or negative voltage in a circuit.
The BC547B is rated for a maximum collector current of 100 mA and a collector-emitter voltage of 45 V, making it suitable for low-power applications.
