For a 100 kHz switching frequency, the average gate-drive current needed is roughly 17 mA — well within the capability of a standard driver IC, but the peak current from the driver still needs to handle the Miller plateau. The 170 nC figure also sets the transition-time budget for hard-switched topologies. Junction temperature spans -55°C to 175°C — this is the full automotive under-hood envelope. The 175°C Tj(max) means the part can sit next to an exhaust manifold or in a transmission controller without derating the junction temperature prematurely. The 300 W power dissipation figure assumes an ideal heatsink; real-world continuous dissipation will be lower, governed by the thermal resistance of the mounting interface. ## Lifecycle and sourcing posture For a production BOM, that means no imminent obsolescence risk.","metaTitle":"AUIRFSL3206 HEXFET N-Channel MOSFET, 3mOhm Rds(on), 120A","metaDescription":"AUIRFSL3206 automotive N-channel HEXFET MOSFET, 60V, 120A, 3mOhm Rds(on) at 75A/10V, 170nC gate charge, -55°C to 175°C Tj.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"series":"HEXFET®","power_w":"300.0","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Through Hole","capacitance_uf":"0.0065","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"60.0","Vgs(Th) (Max) @ Id":"4 V @ 150µA","switching_current_a":"120.0","Rds On (Max) @ Id, Vgs":"3mOhm @ 75 A, 10 V","Operating Temperature High":"-55°C to 175°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"170 nC @ 10 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.74","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c30ab72889571a364ee83426b5f19ecd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of AUIRFSL3206?","answer":"This is the conduction-loss spec for sizing the thermal path."},{"question":"Is AUIRFSL3206 obsolete or end-of-life?","answer":"No — the AUIRFSL3206 is listed with an active lifecycle status."},{"question":"What is the gate charge of AUIRFSL3206?","answer":"This determines the driver current needed for a given switching frequency."},{"question":"What is the maximum operating temperature for AUIRFSL3206?","answer":"The junction temperature range is -55°C to 175°C, covering automotive under-hood and industrial high-temperature environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/AUIRFSL3206","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/AUIRFSL3206 when reusing this data.
