The PMBT3904 is an NPN bipolar junction transistor (BJT) commonly used for switching and amplification purposes. It typically comes in a SOT-23 package, which has three pins. The pin configuration is as follows:
1. Pin 1 (Base): This pin controls the transistor’s operation. A small current applied to the base allows a larger current to flow between the collector and the emitter.
2. Pin 2 (Emitter): This is where the current exits the transistor. It is typically connected to the ground in common-emitter configurations.
3. Pin 3 (Collector): This is the main current-carrying terminal. The collector current is controlled by the base current and flows out of this terminal when the transistor is in the active region.
The PMBT3904 is commonly used in low-power switching applications and can handle collector currents up to 200 mA and voltages up to 40 V. It offers good gain characteristics, making it suitable for amplification tasks in various electronic circuits.

The PMBT3904 is manufactured by Nexperia, a global semiconductor company. Nexperia specializes in producing discrete and MOSFET components, as well as analog and logic ICs.
