It is designed for high-current switching in 12 V and 24 V automotive systems—motor drives, DC-DC converters, battery isolation, and solenoid drivers—where its 55 V drain-source breakdown and 75 A continuous drain rating provide the headroom for transient-rich environments like engine bays and chassis-mounted controllers. ## 5.3 mOhm Rds(on) — what it means for conduction losses At 75 A continuous, the I²R loss is under 30 W, which the 330 W package dissipation ceiling handles with a properly heatsinked TO-220. The gate charge of 260 nC at 10 V means the gate driver must deliver a 2.6 µC pulse to switch the device; a standard automotive gate-driver IC with 2 A peak source will turn it on in roughly 130 ns. ## Automotive temperature grade and construction The HEXFET stripe-cell architecture keeps the Rds(on) positive-temperature-coefficient characteristic, which helps parallel operation and prevents thermal runaway at high current. The TO-220AB package is a standard through-hole power package, compatible with existing heatsink clips and PCB layouts for 75 A-class designs. ## Lifecycle and sourcing posture No last-time-buy or phase-out risk is indicated for this order code.","metaTitle":"Infineon AUIRF1405-INF N-Channel HEXFET MOSFET","metaDescription":"Infineon AUIRF1405-INF automotive N-channel HEXFET MOSFET: 55V Vdss, 75A continuous drain, 5.3mOhm Rds(on) at 101A.
