The MMBT3904 is a general-purpose NPN small-signal transistor manufactured by Diotec Semiconductor. It is designed for medium-power amplification and switching applications.
Key electrical specifications include a maximum collector-emitter voltage of 40V and a continuous collector current of 200mA. The transistor offers a minimum DC current gain (hFE) of 100 at 10mA and 1V, with a Vce saturation of 300mV maximum at 5mA and 50mA. It operates at frequencies up to 300MHz.
This device is housed in a compact SOT-23-3 (TO-236) surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -55°C to 150°C. The power dissipation is rated at 350mW at 25°C ambient temperature.
The MMBT3904 is noted as being totally lead-free and fully RoHS compliant, as well as halogen and antimony free, qualifying it as a "Green" device.
