Transistor circuit for amplifier

Transistor circuit for amplifier

This is the transistor circuit for amplifier using driver circuit. we can use transistors as we want. like one pair to 100 pair. the output watts will depend on the voltage and amperes. transistors can’t increase the output watts. transistor just makes the sound lower to higer using the volts and amperes. 

2sc5200 Polarity is NPN. Max Collector Power Dissipation is 150 Watts. The Max Collector-Base Voltage is 250 Voltage. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 17 amperes. 

2sa1943 Polarity is PNP. The Maximum Collector Power Dissipation is 150 Watts. The Maximum Collector-Base Voltage is 250 Volts. The Maximum Collector-Emitter Voltage is 250 Volts. The Maximum Emitter-Base Voltage is 5 Volts. The Maximum Collector Current is 17 amperes. 

Driver circuit for transistor amplifier

 

This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
