STMicroelectronics, Inc. Single Bipolar Transistors 2N3906

The 2N3906 is a PNP silicon epitaxial planar transistor for through-hole PCB assembly, designed for use as a small load switch with high gain and low saturation voltage. It is housed in a TO-92 package measuring up to 4.95 mm in diameter and 15.49 mm in length. The collector-emitter voltage rating is -40 V, the collector current is -200 mA, and the total power dissipation is 625 mW at 25°C. The maximum junction temperature is 150°C, with a thermal resistance junction-to-ambient of 200°C/W. The DC current gain (hFE) ranges from 30 to 300 depending on operating conditions, and the transition frequency is 250 MHz.
