The Infineon IRFU220NPBF is a N-MOSFET (Transistor) unipolar (affecting only one type of charge carrier) with a maximum drain-source voltage of 200V, a rated drain current of 5A, a power dissipation rating of 43W and a package type of IPAK. The N-channel MOSFET device in this package is designed for output stages in power control circuits, load switching circuits, and DC-DC converters (buck, boost, buck-boost, flyback). It has a low RDS(on) to ensure greater efficiency, an integrated body diode with soft recovery behavior, high current carrying capability and fast switching.
