Total gate charge Qg is 44 nC at 10 V. A 44 nC gate at 100 kHz switching frequency draws 4.4 mA from the gate driver — well within the capability of a standard MOSFET driver IC. The 640 pF input capacitance at 25 V drain-source helps the designer estimate the gate-drive power and switching transition times. ## 175 °C junction rating — high-temperature environments covered The 175 °C maximum allows this part to run in under-hood automotive compartments, industrial motor drives, or sealed power supplies where ambient temperatures exceed 85 °C. The 79 W power dissipation at case temperature assumes an adequate heatsink; derate linearly above 25 °C per the datasheet curve. ## Active production, ROHS3, and the IPAK footprint It is ROHS3 compliant, with no lead-free exemption expiry to track. The IPAK (TO-251AA) package uses a through-hole mounting style; the short leads reduce board height compared to a standard TO-220, suiting it for space-constrained assemblies.","metaTitle":"IRFU3910PBF N-Channel MOSFET, 100 V, 16 A, 115 mOhm","metaDescription":"Infineon IRFU3910PBF HEXFET N-channel MOSFET, 100 V Vdss, 16 A Id, 115 mOhm Rds(on), 44 nC Qg.
