At 7.3 mOhm with a 10 V gate drive, conduction losses stay low even at 52 A load current. The drive voltage window of 6 V to 10 V lets you trade off Rds(on) against gate-drive complexity: 10 V gives the lowest on-resistance; 6 V still works but at higher resistance. ## Thermal derating and mounting The 143 W maximum power dissipation is specified at the case temperature — that number assumes a heatsink with good thermal interface. In a real enclosure, derate the continuous current from 87 A based on the junction-to-case thermal resistance and ambient conditions. The TO-220AB package fits standard clip or screw-mount heatsinks; the through-hole leads suit wave-solder assembly on FR4 or metal-core boards. It is ROHS3 compliant. The StrongIRFET™ series is a current-production family.","metaTitle":"IRFB7740PBF StrongIRFET N-Ch 75V 87A TO-220AB MOSFET","metaDescription":"IRFB7740PBF StrongIRFET N-channel MOSFET, 75V Vdss, 87A Id, 7.3mOhm Rds(on) at 10V.
