The onsemi MMBT3904K is a general-purpose NPN bipolar junction transistor (BJT) designed for surface-mount applications. This component features a collector-emitter breakdown voltage of 40V and a maximum continuous collector current of 200mA. With a transition frequency of 300MHz and a power dissipation of 350mW, it is suitable for a wide range of amplification and switching tasks. The device is housed in a compact SOT-23-3 package, facilitating high-density board designs. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at 10mA collector current and 1V collector-emitter voltage, and a Vce(sat) of 300mV at 5mA base current and 50mA collector current. Operating temperature range is from -55°C to 150°C. This transistor is commonly utilized in consumer electronics, industrial control systems, and communication infrastructure. The MMBT3904K is supplied in Tape & Reel packaging.
