The CPC3710C is a high-power, high-gain type Class AB complementary FET (Field-Effect Transistor) designed for audio power applications from 1 to 500 watts. It can be used in many configurations, including full bridge, push-pull and serpentine series circuits. The device is ideal for applications such as power amplifiers, audio monitors and speaker systems. It is also suitable for use in automotive audio systems, where the sound quality and the power handling capacity of the components must be kept high. The CPC3710C offers high efficiency, low distortion and excellent thermal stability.

Working Principle

The CPC3710C is a N-channel MOSFET (Metal Oxide Field-Effect Transistor). It has two source terminals and one drain terminal, and it operates in the enhancement mode. This device is a self-biased FET, which means that the drain-to-source voltage and the gate bias voltage are externally adjustable. The device has an on-resistance of about 0.4 ohms and a drain current of about 21 amperes. It is capable of providing up to 500 watts of output power.

The CPC3710C is a high-power type class AB (complementary) FET. It works by allowing current to flow through its drain-source terminals when the gate-source voltage is made positive by applying a positive voltage to the gate. The device has a built-in diode which prevents current from flowing back into the gate, which would cause it to become damaged. It also has a series resistance which ensures that the drain-source voltage remains constant even when the gate voltage changes. This ensures that the device operates in its safe region.

Application Field

The CPC3710C is a high-power, high-gain type FET specifically designed to meet the needs of power amplifiers, audio monitors and speaker systems. Its high power handling capacity together with its low distortion capabilities make it ideal for audio applications. The device is also suitable for automotive audio systems, where the sound quality and the power handling capacity of the components must be kept high. It is also used in other circuit designs, such as power supplies and switching power supplies.

The CPC3710C is also used in switching power supplies. Its self-biased gate configuration makes it suitable for use in simple buck or boost topologies. Its low on-resistance and its low gate charge ensure high efficiency and low heat dissipation. Its high-power rating and its built-in diode make it ideal for applications such as DC-DC converters, switching regulators and motor drives.

In addition, the CPC3710C is used in RF (radio-frequency) and microwave amplifier circuits. Its low output capacitance allows it to be used in frequency-dependent applications such as oscillators and mixers. The device is also used in the power stages of high power RF linear amplifiers, where its high gain and low noise performance ensures efficient operation.
