BC547 CDIL Transistor. For switching and AF amplifier application, ABSOLUTE MAXIMUM RATINGS (Ta=25ºC unless specified otherwise)
A transistor is basically an electrically controlled switch. The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit. The BC547 is a widely used transistor and it can be used in any general purpose application, it can also be used as a substitute and replacement to many transistors, therefore it can be used in variety of electronic circuits for example switch small load on very low input voltage and current and also in amplification of small audio and other signals. The max transition frequency of the transistor is 300MHz so it will also perform well in RF circuits under 300MHz frequency.
