BC650

The BC650 is designed as one kind of NPN silicon low noise audio transistors.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its collector to maximum voltage would be 30Vdc. (2)Its collector to base voltage would be 30V. (3)Its emitter to base voltage would be 6.0V. (4)Its collector current continuous would be 200mAdc. (5)Its total device dissipation at Ta=25°C would be 625mW. (6)Its Its total device dissipation at Ta=25°C derate above 25°C would be 5.0mW/°C. (7)Its total device dissipatiob at Tc=25°C would be 1.5W. (8)Its total device dissipation at Tc=25°C derate above 25°C would be 12mW/°C. (9)Its operating temperature range would be from -55°C to 150°C. (10)Its junction temperature range would be from -55°C to 150°C. (11)Its storage temperature range would be from -55°C to 150°C. (12)Its thermal resistance junction to case would be max 83.3°C/W. (13)Its thermal resistance junction to ambient would be 200°C/W. It
should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)Its collector to emitter breakdown voltage would be min 30V. (2)Its collector to base breakdown voltage would be min 30V. (3)Its collector cutoff current would be max 0.015uA. (4)Its collector to emitter leakage current would be max 0.025uA. (5) Its emitter cutoff current would be max 0.015uA. (6)Its DC current gain would be min 380 and typ 1400. (7)Its collector to emitter saturation voltage would be max 0.2Vdc with conditions of Ic=10mA and Ib=0.5mA and it would be max 0.6V with conditions of Ic=100mA and Ib=5.0mA. (8)Its base emitter on voltage would be min 0.55V and max 0.7V. (9)Its small signal current gain would be min 380 and max 1600. (10)Its outout capacitance would be max 3.0pF. (11)Its input capacitance would be max 8.0pF. (12)Its current gain bandwidth product would be min 100MHz and max 700MHz. (13)Its noise figure would be max 2.8dB. And so on.
