These numbers define the gate-drive power and switching speed — the 60 nC Qg means a 1 A gate driver can switch the gate in about 60 ns, but the 1360 pF Ciss adds to the driver's reactive load. The IRFZ44ESTRRPBF is listed as obsolete. Buyers should qualify an alternate N-channel MOSFET in the same 60 V / 48 A class and D²Pak footprint for new designs or long-term production support.","metaTitle":"IRFZ44ESTRRPBF HEXFET® N-Channel MOSFET, 60V 48A D²Pak","metaDescription":"Infineon IRFZ44ESTRRPBF N-channel HEXFET® MOSFET, 60V Vdss, 48A Id, 23mOhm Rds(on).
