Sourcing is limited to the surplus and broker channel, where independent distributors stock remaining inventory. The 60 V drain-to-source voltage rating places this MOSFET in the 48 V bus and 12 V/24 V automotive power domain, with margin for load-dump transients in 12 V systems. Gate charge is 67 nC at 10 V, which determines the drive power required from the gate driver and influences switching speed. Input capacitance is 1812 pF at 25 V drain-source, a moderate value that allows reasonable switching frequencies without excessive driver current. ## Temperature range and package — deployment environment","metaTitle":"IRFZ44VSTRR N-Channel MOSFET, 60V, 55A, D2PAK, Obsolete","metaDescription":"IRFZ44VSTRR is an obsolete N-Channel HEXFET MOSFET with 60V Vdss, 55A continuous drain current, 16.5 mOhm RDS(on) at 10V.
