| 2N3903 Discrete POWER & Signal Technologies 2N3903 C BE TO-92 NPN General Purpose Amplifier This device is designed for use as general purpose amplifiers and switches requiring collector currents to 100 mA. Sourced from Process 23. See 2N3904 for characteristics. Absolute Maximum Ratings* Symbol VCEO VCBO VEBO IC TJ, Tstg Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25C unless otherwise noted Parameter Value 40 60 6.0 200 -55 to +150 Units V V V mA C Operating and Storage Junction Temperature Range *These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 150 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
