2N2905 Description

Short technical summary and product information.

The 2N2905 is a PNP bipolar junction transistor (BJT) manufactured by Texas Instruments, housed in a TO-39 metal package. It is designed for high-speed saturated switching and general-purpose applications, as well as driver applications in industrial service.

Key electrical characteristics include a maximum collector-base voltage (VCBO) of 60V and a maximum collector-emitter voltage (VCEO) of 40V for the 2N2905 variant. The continuous collector current (IC) is rated up to 600mA, with a peak collector current (ICM) of 800mA. The DC current gain (hFE) ranges from 100 to 300 at IC = -150mA and VCE = -10V. The transition frequency (fT) is a minimum of 200MHz under specified conditions.

Thermal performance is supported by a junction-to-ambient thermal resistance of 292 K/W and a junction-to-case thermal resistance of 58 K/W. The operating ambient temperature range is -65°C to +150°C.

This transistor is suitable for applications requiring fast switching speeds and moderate current handling capabilities.
