It is qualified to AEC-Q101, making it a direct fit for automotive power-train, DC-DC converter, and motor-drive stages where junction temperatures can reach 175°C. The 1.8 mOhm maximum on-resistance at 10 V gate drive keeps conduction losses low in high-current paths, which directly affects heatsink sizing and PCB copper budgeting. ## Gate drive and switching considerations Gate threshold is 4 V at 150 µA; maximum gate-source rating is ±20 V. Total gate charge is 225 nC at 10 V. ## Package and mounting The D2PAK (TO-263) surface-mount package allows reflow assembly and is suited for automated production lines. The large drain tab provides a low thermal resistance path to the PCB; a thermal via array under the tab is recommended to keep junction temperature within the 175°C limit under full load. ## Lifecycle and sourcing The AUIRFS8407TRR is listed as Active in production, so there is no last-time-buy risk for current or new designs.","metaTitle":"AUIRFS8407TRR MOSFET N-CH 40V 195A D2PAK, AEC-Q101","metaDescription":"Infineon AUIRFS8407TRR N-channel MOSFET, 40V, 195A, 1.8mOhm Rds(on), AEC-Q101 qualified, 175°C TJ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Vgs":"±20 V","series":"Automotive, AEC-Q101, HEXFET®","power_w":"230.0","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Surface Mount","capacitance_uf":"0.0073","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"40.0","Vgs(Th) (Max) @ Id":"4 V @ 150µA","switching_current_a":"195.0","Rds On (Max) @ Id, Vgs":"1.8mOhm @ 100 A, 10 V","Operating Temperature High":"-55°C to 175°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"225 nC @ 10 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.09","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38d7cc666c464a0f20811245258b0a08.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is AUIRFS8407TRR AEC-Q101 qualified?","answer":"Yes, the AUIRFS8407TRR is part of the Automotive, AEC-Q101 qualified HEXFET® series, making it suitable for automotive-grade applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/AUIRFS8407TRR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/AUIRFS8407TRR when reusing this data.
