BC338 NPN Transistor

The BC338 is a widely used NPN epitaxial silicon transistor, packaged in a standard TO-92 form factor. It is designed for general-purpose amplification and switching tasks in low-power electronic circuits. This transistor features a maximum collector current (IC) of 800mA and a collector-emitter voltage (VCEO) of 25V, making it suitable for driving relays, LEDs, and small motors in hobbyist and educational projects. Key characteristics include a DC current gain (hFE) ranging from 100 to 600, a transition frequency (fT) of 100MHz, and low saturation voltage. Its robust design ensures reliable performance in prototyping environments like Arduino and Raspberry Pi interfaces. Common applications include audio pre-amplifiers, signal processing, logic gates, and driver stages in power supplies. Choose the BC338 for its cost-effectiveness, wide availability, and compatibility with numerous circuit designs. It is an excellent choice for hobbyists, students, and engineers looking for a dependable, general-purpose NPN transistor for breadboarding and PCB assembly.
