BC547B

This device is an NPN silicon amplifier transistor in a TO-92 package. It is rated for 45 V collector-emitter voltage, 50 V collector-base voltage, 6.0 V emitter-base voltage, and 100 mA continuous collector current. Total device dissipation is 625 mW at 25°C ambient, and the operating and storage junction temperature range is -55°C to +150°C. The BC547B gain group is specified for 200 to 450 DC current gain at IC = 2.0 mA and VCE = 5.0 V, with a typical transition frequency of 300 MHz. Typical output capacitance is 1.7 pF and typical noise figure is 2.0 dB under the stated test conditions.
