2N2905A
2N2907A
GENERAL PURPOSE AMPLIFIERS AND SWITCHES
DESCRIPTION
The 2N2905A and 2N2907A are silicon planar
epitaxial PNP transistors in Jedec TO-39 (for
2N2905A) and in Jedec TO-18 (for 2N2907A)
metal case. They are designed for high speed
saturated switching and general purpose
applications.
2N2905A approved to CECC 50002-100,
2N2906A approved to CECC 50002-103
available on request.
