onsemi Single Bipolar Transistors 2N3904

The 2N3904 is an NPN silicon transistor in a TO-92 package, designed for general-purpose amplification and switching applications. It has a collector-emitter voltage rating of 40 Vdc, a collector current rating of 200 mAdc, and a total device dissipation of 625 mW at 25°C, derating at 5.0 mW/°C above that temperature. The junction temperature range is -55°C to +150°C. Thermal resistance from junction to ambient is 200 °C/W. DC current gain ranges from 30 to 300 depending on collector current, with a collector-emitter saturation voltage of 0.3 Vdc at 50 mAdc collector current and 5 mAdc base current. The current-gain bandwidth product is 300 MHz, and output capacitance is 4.0 pF. The package dimensions and mounting style are consistent with the TO-92 case, style 1, with straight or bent leads.
