2N3904 PDF Specs and Replacement

The 2N3904 is one of the most widely used NPN bipolar junction transistors in low-power electronic circuits. Designed for general-purpose amplification and switching, it offers a reliable balance of performance, robustness, affordability, making it a staple in prototyping and commercial designs. The transistor supports a collector current up to 200mA and a collector-emitter voltage of 40V, allowing it to handle small signal stages, sensor interfaces, and digital switching tasks. With a typical DC current gain from 100 to 300, the 2N3904 efficiently amplifies low-level signals while maintaining stable operation across a broad temperature range. Thanks to its high switching speed, it is frequently used in oscillator circuits, pulse generators, and driver stages for LEDs and relays. Its standard TO92 package ensures easy integration on breadboards and PCBs. The 2N3904 remains a dependable choice for engineers and hobbyists who need a versatile, predictable transistor for everyday electronic applications.
