200W MOSFET Amplifier based IRFP250N

200W MOSFET Amplifier based IRFP250N Circuit Design
Here is the 200W MOSFET amplifier powered based on four piece of IRFP250N, they are very cheap and easy to find in the electronic market in your area. The circuit has been assembled and tested with very good performance.

This 200W MOSFET amplifier circuit designed for single or mono audio channel application. You should build two similar circuits for stereo audio application. Build one first for performance testing to ensure that this circuit really wongking well with great audio performance.

The power supply used for this circuit is a symmetrical / dual polarity type. You need 4 amperes minimum of transformer with +/- 45V output. For stereo application, use about 8 amperes, although the 5A transformer is good enough 😀 . You may use the power supply circuit design on this post: 200W Power Amplifier using Transistor

200W MOSFET Amplifier based IRFP250N PCB Design

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) power audio amplifier is an amplifier circuit that utilizes MOSFETs as the main active components for amplifying audio signals. MOSFETs are a type of transistor widely used in electronic circuits for various applications, including power amplifiers.

In the context of power audio amplifiers, MOSFETs can be employed in the output stage of the amplifier circuit. The output stage is responsible for delivering power to the speakers and is a crucial component in determining the overall performance of the amplifier.
