60W MOSFET Audio Amplifier

General Description:

• MPSA43 – NPN high voltage transistor with low current and high voltage used for telephony, professional communication equipment, and telephony, and is the complement type of MPSA93
• MJE350 – a plastic medium power PNP silicon transistor designed for use in line-operated applications such as low power, line-operated series pass and switching regulators requiring PNP capability with features of high collector-emitter sustaining voltage, excellent DC current gain, and plastic thermopad package
• IRFP240 – an N-channel enhancement mode silicon gate power field effect transistor with an advanced power MOSFET designed, tested, and guaranteed to withstand a specified level of energy in the breakdown avalanche mode of operation used in applications such as switching regulators, switching converters, motor drivers, relay drivers, and drivers for high power bipolar switching transistors requiring high speed and low gat drive power due to features of high input impedance, linear transfer characteristics, nanosecond switching speeds, limited power dissipation, and single pulse avalanche energy rated

     The 60W MOSFET audio amplifier may be used in automotive sound systems, home theater entertainment systems, and audio-video receivers to continually improve the quality of the audio. redcircuits.com/Page100.htm
