It carries AEC-Q101 qualification and a 175°C maximum junction temperature, placing it in the under-hood and chassis-domain tier of automotive power switching. The 3.1 mOhm max on-resistance at 76 A and 10 V gate drive keeps conduction losses low enough for motor-drive, solenoid, and DC-DC converter outputs where board space and heatsinking are tight. ## Gate drive and switching Gate-source voltage is rated to ±20 V. Total gate charge is 99 nC at 10 V. Input capacitance is 0.0032 µF. ## Thermal and package The 99 W power dissipation rating and 175°C Tj maximum are specified. Through-hole mounting provides thermal transfer to a heatsink. ## Lifecycle and sourcing The AUIRFU8403-701TRL is listed as Active with no end-of-life notice.","metaTitle":"AUIRFU8403-701TRL Automotive N-Channel MOSFET, 40V, 100A","metaDescription":"Infineon AUIRFU8403-701TRL N-Channel HEXFET power MOSFET, 40V, 100A, 3.1mOhm Rds(on), AEC-Q101 qualified, -55 to 175°C.","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":"99.0","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Through Hole","capacitance_uf":"0.0032","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"40.0","Vgs(Th) (Max) @ Id":"3.9 V @ 100µA","switching_current_a":"100.0","Rds On (Max) @ Id, Vgs":"3.1mOhm @ 76 A, 10 V","Operating Temperature High":"-55°C to 175°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"99 nC @ 10 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.89","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bfcc9093688761d9da0d8501bb97335.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is AUIRFU8403-701TRL AEC-Q101 qualified?","answer":"Yes, the AUIRFU8403-701TRL is AEC-Q101 qualified and part of Infineon's Automotive HEXFET series, making it suitable for automotive under-hood and chassis-domain applications."},{"question":"What is AUIRFU8403-701TRL's listed Vgs?","answer":"The gate-source voltage rating is ±20 V, allowing direct drive from 12 V automotive battery rails without external clamping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/AUIRFU8403-701TRL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/AUIRFU8403-701TRL when reusing this data.
