2N3905 Description

Short technical summary and product information.

The 2N3905 is a PNP bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications. Key electrical specifications include a maximum collector-emitter voltage (Vceo) of 40V, a maximum collector current (Ic) of 200mA, and a maximum power dissipation (Pd) of 625mW. The transistor offers a DC current gain (hFE) of 50 minimum at Ic=10mA and Vce=1V, and a transition frequency (ft) of 200MHz. The collector-emitter saturation voltage is 400mV maximum at Ib=5mA and Ic=50mA. The device is housed in a TO-226-3 / TO-92-3 (TO-226AA) package and is through-hole mountable, with a supplier device package of TO-92. It operates over a junction temperature range of -55°C to 150°C. This transistor is suitable for low-power switching and signal amplification in a variety of electronic circuits.
