PCB layout driver 250 watts using transistor:

The PCB layout driver 250 watts using transistor MJ15003 and MJ15004. This pair of transistors can produce 250 watts of 50-0-50 voltage and 5 amperes. voltage X ampere= 50X5=250. we also can use 25-0-25 to 70-0-70 voltage. it’s a mono audio amplifier circuit diagram. the output is 4 ohms.

Details about MJ15003

mj15003 Polarity is NPN. Max Collector Power Dissipation is 200 Watts. The Max Collector-Base Voltage is 140 Voltage. Max Collector-Emitter Voltage is 140 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 20 amperes.

Details about MJ15004

mj15004 Polarity is PNP. Max Collector Power Dissipation is 200 Watts. The Max Collector-Base Voltage is 140 Voltage. Max Collector-Emitter Voltage is 140 Voltage. The Max Emitter-Base Voltage is 5 Voltage. Maximum Collector Current is 20 amperes.

Here we can see that the maximum voltage is 250, which can throw the Emitter and Collector. The base can take 5 voltages. and the voltage ampere can take a maximum of 17.

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.
