The 4.25 mOhm Rds(on) at 60 A keeps conduction losses low in high-current paths like motor-drive bridges, battery disconnect switches, and DC-DC converter primary switches. The 63 nC total gate charge at 10 V means the gate driver needs to source about 6.3 mA per 100 kHz switching frequency — a standard 1 A driver handles it with margin. The 79 W power dissipation rating assumes adequate heatsinking on the I-PAK tab.","metaTitle":"AUIRFU8401 MOSFET N-CH 40V 100A I-PAK, Active","metaDescription":"AUIRFU8401 N-channel HEXFET MOSFET, 40 V, 100 A, 4.25 mOhm Rds(on), I-PAK through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Vgs":"±20 V","series":"HEXFET®","power_w":"79.0","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Through Hole","capacitance_uf":"0.0022","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"40.0","Vgs(Th) (Max) @ Id":"3.9 V @ 500µA","switching_current_a":"100.0","Rds On (Max) @ Id, Vgs":"4.25mOhm @ 60 A, 10 V","Operating Temperature High":"-55°C to 175°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"63 nC @ 10 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.61","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5f3d1671a6741d15145a6ce303f5725b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of AUIRFU8401?","answer":"Maximum Rds(on) is 4.25 mOhm at 60 A drain current and 10 V gate drive."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/AUIRFU8401","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/AUIRFU8401 when reusing this data.
