It is rated for a drain-to-source voltage of 60 V and a continuous drain current of 55 A at 25°C case temperature. The 16.5 mOhm maximum on-resistance, specified at 31 A and 10 V gate drive, makes it a fit for medium-voltage switching regulators, DC-DC converters, motor drives, and battery management circuits where conduction losses matter. The 67 nC gate charge at 10 V tells you the driver must deliver enough peak current to switch the FET cleanly at frequency. ## NRND — not for new designs If you have an active design using this order code, plan for a last-time-buy or identify a replacement before the end-of-life notice arrives. The part remains ROHS3 compliant. The 60 V Vdss is the maximum drain-to-source voltage. The 115 W maximum power dissipation at case temperature 25°C requires a heatsink for any continuous load above a few amps — the TO-220AB tab is the primary thermal path, and a proper thermal interface to the heatsink is non-negotiable for sustained high-current operation.","metaTitle":"IRFZ44VPBF HEXFET N-Channel MOSFET, 60V 55A TO-220AB","metaDescription":"IRFZ44VPBF N-channel MOSFET from the HEXFET series. 60V Vdss, 55A Id, 16.5mOhm Rds(on).
