DIY driver circuit diagram:
This is the DIY driver circuit diagram for the amplifier. This circuit can make an amplifier using 20 transistors. This board is not an amplifier. It’s just a sound driver. It drives the sound to transistors. We can use any of the PNP and NPN transistors to make an amplifier. like 2sc5200 and 2sa1943. or c5198 and a1941. or TIP41 and TIP41. any of the transistors according to the voltage and amperes.
Details about 2SC5200
2sc5200 Polarity is NPN. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Details about 2SA1943
2sa1943 Polarity is PNP. Max Collector Power Dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Details about C5198
C5198 Polarity is NPN. The maximum collector power dissipation is 100 watts. The maximum collector-base Voltage is 140 volts. Max Collector-Emitter Voltage is 140V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 10 amperes.
Details about A1941
2sa1941 Polarity is PNP. Max Collector Power Dissipation is 100 Watts. The maximum collector-base Voltage is 140 volts. Max Collector-Emitter Voltage is 140V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 10 amperes.
Transistor circuit for an amplifier
This is the transistor circuit for an amplifier using a driver circuit. We can use transistors as we want. like one pair to 100 pairs. The output watts will depend on the voltage and amperes. Transistors can’t increase the output watts. The transistor simply amplifies the sound, increasing the voltage and current.
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.
