Discrete POWER & Signal Technologies NPN General Purpose Amplifier BC547 BC547A BC547B BC547C 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* TA = 25°C unless otherwise noted Lushprojects.com transistor amplifier Circuit Diagram Take two bc547 transistors and connect the emitter pin of the first transistor with the base pin of the second transistor. Connect a 10K-ohm resistor between the base and collector pin of the first transistor. Join the negative wire of the speaker with the collector pin of the first transistor as shown above. In several cases the sound generated is not clearly audible and hence it is required to increase the intensity level so that it can be further used. This circuit based [[wysiwyg_imageupload::]]project demonstrates the principle and operation of a simple sound amplifier. The circuit is divided into three parts: 1.Sensor, 2.Amplifier, and 3. Output.Sensor converts the physical characteristics of BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC547 Transistor Pinout Configuration BC547 Transistor Features Bi-Polar NPN Transistor DC Current Gain (h FE) is 800 maximum Step 7: Connect Power Supply Wire. Next connect 5V DC Power supply wire to the circuit. NOTE : We can give input power supply with 5V charger,5V battery,..5VDC. Connect +ve clip of power supply to collector pin of transistor-1 and. -ve clip to emmiter pin of transistor-2 as you can see in the picture.

BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
