Working Principle

FCB070N65S3 is an N-channel enhancement mode MOSFET. The internal construction of an N-channel MOSFET consists of three regions; source, gate and drain. This type of transistor has the ability to allow electrical current to flow between the source and drain terminals when a voltage is applied to the gate terminal.

When the voltage applied to the gate is positive, an electric field is created that attracts more electrons from the source to the gate. This creates a conductive channel through which current can flow from the source to the drain. This is known as the "on" state of the device.

When the voltage applied to the gate is negative, the electric field is reversed, and the electrons are attracted back to the source, This depletes the conductive channel and the device is said to be in the "off"state.

The operation of FCB070N65S3 is based on this principle. The on/off state is determined by the voltage applied to the gate terminal. This makes it ideal for performing switching functions in many applications.

FCB070N65S3, as part of the N-channel enhancement mode MOSFET family, offers the advantages of fast switching, low gate threshold voltage and high surge current capability. It is suitable for use in high reliability applications, such as automotive systems, motor drives, light dimmers, solar inverters and off-line power supplies.
