onsemi Single Bipolar Transistors 2N3906

The 2N3906 is a PNP silicon transistor designed for general-purpose switching and amplification applications. It is packaged in a TO-92 case with straight or bent leads, measuring up to 5.20 mm in body width and 12.70 mm in lead length. The device has a collector-emitter voltage rating of 40 V, a continuous collector current of 200 mA, and a total power dissipation of 625 mW at 25°C, derating at 5.0 mW/°C above that temperature. The thermal resistance from junction to ambient is 200 °C/W. Current gain (hFE) ranges from 30 to 300 depending on collector current, with a transition frequency of 250 MHz and an input capacitance of 10 pF. The part meets RoHS compliance in its lead-free variants. Operating and storage junction temperatures range from -55°C to +150°C.
