The 6 mOhm max on-resistance at 71 A and 10 V gate drive determines conduction loss. ## Temperature range and environment Rated for a junction temperature range of -55°C to 175°C, this MOSFET suits under-hood automotive, industrial motor-drive, and power-supply environments. The 175°C maximum junction temperature is the absolute ceiling. ## Lifecycle and sourcing No official second-source or pin-compatible alternate is listed in the available records, so dual-sourcing would require qualification of a functionally equivalent 30 V N-channel in the same D²Pak footprint.","metaTitle":"IRL3803SPBF HEXFET N-Channel MOSFET, 30 V, 140 A, 6 mOhm","metaDescription":"IRL3803SPBF HEXFET N-Channel MOSFET: 30 V drain-source, 140 A switching current, 6 mOhm Rds(on) max at 71 A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Vgs":"±16 V","series":"HEXFET®","power_w":"3.8","Fet Type":"N-Channel","package_type":"Bulk","mounting_type":"Surface Mount","capacitance_uf":"0.005","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"30.0","Vgs(Th) (Max) @ Id":"1 V @ 250µA","switching_current_a":"140.0","Rds On (Max) @ Id, Vgs":"6mOhm @ 71 A, 10 V","Operating Temperature High":"-55°C to 175°C(TJ)","Gate Charge (Qg) (Max) @ Vgs":"140 nC @ 4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.46","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ce5a77e806ebb9a496a5ddcf1aff619.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRL3803SPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRL3803SPBF when reusing this data.
