Pinout

The PMST3904 is a general-purpose NPN bipolar junction transistor. It typically comes in a SOT-23 package, which has three pins. Here is a brief description of each pin and its function:
1. Pin 1 (Emitter): This is the emitter terminal of the transistor. Current flows out of this terminal in an NPN transistor.
2. Pin 2 (Base): This is the base terminal, which controls the transistor's operation. A small current or voltage applied to the base controls the larger current flow between the collector and emitter.
3. Pin 3 (Collector): This is the collector terminal. Current flows into this terminal from the load.
The PMST3904 is widely used for switching and amplification purposes due to its ability to handle moderate current and voltage levels.
