Its 6.5 mOhm maximum on-resistance at 15 A with a 10 V gate drive keeps conduction losses low in DC-DC converters, load switches, and motor pre-drive stages — the kind of circuit where every milliohm of Rds(on) shaves a fraction of a watt off the thermal budget. The 100 A pulsed drain current rating covers inrush events and capacitor pre-charge without oversizing the FET, but the continuous current is package-limited; the designer sizes the copper pad area accordingly. ## Gate drive and switching — 44 nC at 4.5 V Gate charge of 44 nC at 4.5 V. The ±20 V Vgs maximum gives headroom for gate-drive transients. ## Lifecycle and sourcing That makes it a clean choice for BOM freeze and production qualification. For dual-sourcing or supply resilience, the DPAK footprint is shared across the Infineon HEXFET family; a pin-compatible sibling with a different Rds(on) tier can be qualified without a board respin.","metaTitle":"IRFR3711TRLPBF HEXFET N-Channel MOSFET, 6.5 mOhm Rds(on)","metaDescription":"IRFR3711TRLPBF N-channel HEXFET power MOSFET. 6.5 mOhm Rds(on) at 15 A, 100 A pulsed, -55 to 150 °C Tj.
