TELEPHONE: (973) 376-2922 (212)227-6005 FAX: (973) 376-8960 POWER TRANSISTOR GERMANIUM PNP POWER TRANSISTOR 2N297A is a germanium PNP alloy junction power t r a n s i > t o r m e r t i n g m i l i t a r y specification MlL-T-19500 36A f S i g O ) . The m a x i m u m collector-emitter voltage rating is 50 volts, and the collector c u r r e n t rating is 5 amperes. . 2X297A will readily dissipate .'55 watts at 25 C and 10 watts at 75"C. High current switching, audio amplification, small motor and servo drivers are typical applications for the transistor, There are numerous other applications to regulators, power supply and oscillator circuits, 2N297A transistor features welded construction and cadmium plating with a vacuum-tight seal to insure long life and stable operation. Mechanical dimensions conform to the JEDEC TO-3 outline. ABSOLUTE MAXIMUM RATINGS V CE Vdc Vcu Vdc Ic Adc P.
