Working Principle of IRFU4615PBF

The IRFU4615PBF is an N-channel enhancement mode MOSFET, which means it is composed of a p-type gate, n-type body, and n-type source and drain regions. This four-terminal device is connected to a source of power and a load, and the source and drain are connected in series with the load. When a positive voltage is applied to the gate region, electrons in the channel between the source and drain regions are attracted to the gate region, creating an inversion layer and allowing the flow of current through the channel. This current is regulated by the voltage applied to the gate, allowing for current control in applications such as motor control and AC-DC power supply converters.
