500 watts amplifier diagram:
This is a 500-watt amplifier diagram. This circuit can produce 500 watts using 2sc2922 and 2sa1216. Those sunken transistors can make a good watt. here we can use 70-0-70 voltage and 8 amperes. it’s a mono-circuit board. this pair of transistors can make a maximum of 500 watts. we also can use 2sc5200 and 2sa1943 transistors.
The transistor 2SC2922:
The material of the transistor is Si
The polarity is NPN
The maximum Collector Power Dissipation is 200W.
The maximum Collector-Base Voltage is 180V.
The maximum Collector Current max is 17A.
The max operating Junction Temperature is 150 °C.
The transition Frequency is 25 MHz.
The Current Transfer Ratio (hFE), MIN is 33.
The transistor 2SA1216:
The material of the transistor is Si
The polarity is PNP
The maximum Collector Power Dissipation is 200W.
The maximum Collector-Base Voltage is 180V.
The maximum Collector Current max is 17A.
The max operating Junction Temperature is 150 °C.
The transition Frequency is 25 MHz.
The Current Transfer Ratio (hFE), MIN is 33.
The circuit diagram is
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. if the amplifier got 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 the speaker. this circuit is so important to protect the speaker.
