BC547 / BC547A / BC547B / BC547C Discrete POWER & Signal Technologies BC547 BC547A BC547B BC547C E B TO-92 C NPN General Purpose Amplifier This device is designed for use as general purpose amplifiers and switches requiring collector currents to 300 mA. Sourced from Process 10. See PN100A for characteristics. Absolute Maximum Ratings* Symbol VCEO VCES VEBO IC TJ, Tstg Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25°C unless otherwise noted Parameter Value 45 50 6.0 500 -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.
