This means International Rectifier (now Infineon) will not invest in long-term production support for this specific order code, and a last-time-buy window or eventual discontinuation is the expected path. The 60 V Vdss rating places this part in the 48 V / 60 V bus class — suitable for motor drives, DC-DC converters, and battery management in automotive and industrial gear. The 57 A continuous drain current is a package-limited number at 25°C case temperature; real-world current will be lower once you derate for ambient temperature and switching losses. The D2PAK (TO-263) surface-mount package dissipates up to 92 W at the case temperature. Without adequate thermal vias and a copper pour, the junction temperature will exceed the 175°C maximum long before the 57 A current rating is reached.","metaTitle":"IRFZ44VZSPBF N-Channel MOSFET, 60V 57A D2PAK, NRND","metaDescription":"IRFZ44VZSPBF HEXFET N-channel MOSFET: 60V Vdss, 57A Id, 12mΩ Rds(on) at 34A.
