100 watts amplifier circuit diagram:

This is a 100 watts amplifier circuit diagram. This circuit can produce 100 watts using 25-0-25 voltage. 25 voltage 4 amperes. it’s a mono board. for stereo needs dual board. here used 2 transistors. TIP31 and TIP32. TIP31 is a positive transistor. TIP32 is a negative transistor.

Details about TIP31

TIP31 Polarity is NPN. The Maximum Collector Power Dissipation is 40 Watts. The Maximum Collector-Base Voltage is 80 Volts. The Maximum Collector-Emitter Voltage is 40 Volts. The Maximum Emitter-Base Voltage is 5 Volts. The Maximum Collector Current is 3 amperes.

Details about TIP32

TIP32 Polarity is PNP. Max Collector Power Dissipation is 40 Watts. The Max Collector-Base Voltage is 80 Voltage. Max Collector-Emitter Voltage is 80 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 3 amperes.

Here we can see that the maximum voltage is 80, which can throw the Emitter and Collector. The base can take 5 voltages. and the voltage ampere can take a maximum of 3.

This circuit doesn’t have speaker protection. here need a speaker protection circuit. here is the link to get the speaker protection circuit. Diagram is here

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