2n3904 pinout

The 2N3904 is a popular NPN Bipolar Junction Transistor (BJT) that is widely used in electronic circuits. It is designed for general-purpose amplifier and switching applications. With its compact TO-92 packaging, the 2N3904 offers excellent space-saving features and can easily be mounted on a PCB. The 2N3904 has three terminals: the base, collector, and emitter. The base is where the input signal is applied and controls the flow of current between the collector and emitter terminals. It has a maximum collector current of 200mA and a maximum power dissipation of 625mW, making it suitable for low to medium power applications. This transistor is known for its high amplification factor (hfe), which makes it suitable for audio amplification, signal processing, and small-scale switching applications. It operates within a wide range of temperatures and is well-suited for use in industrial and consumer electronics. With its low cost, high availability, and versatility, the 2N3904 is an indispensable component in the world of electronic design and development.
