IRFZ44NPBF Infineon Power MOSFET

The IRFZ44NPBF from Infineon is an N-channel HEXFET® power MOSFET delivering 55V, 49A continuous drain current, and 17.5mΩ max RDS(on) at 10V for minimal conduction loss in high-power switching. For selection, a 63nC gate charge, 1470pF input capacitance, 4V threshold, and 94W dissipation with -55°C to +175°C operation simplify gate-drive design and ensure ruggedness. In application, it excels in DC-DC converters, SMPS, motor drives, inverters, relay/solenoid drivers, LED lighting, battery management, and automotive systems where efficient, reliable medium-power switching is essential.
