The 2.5 W power dissipation at 25°C ambient is the package limit in still air — for continuous 8.5 A operation, derate the current or add copper-area heatsinking on the PCB. Infineon lists the IRF7403TR as obsolete. No direct replacement has been assigned by the manufacturer.","metaTitle":"IRF7403TR N-Channel MOSFET, 30 V, 8.5 A, 22 mOhm, SOIC-8","metaDescription":"Infineon IRF7403TR N-Channel HEXFET MOSFET, 30 V Vdss, 8.5 A Id, 22 mOhm Rds(on), SOIC-8.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"HEXFET®","Package":"Tape & Reel (TR)","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"1V @ 250µA","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"22mOhm @ 4A, 10V","Power Dissipation (Max)":"2.5W (Ta)","Supplier Device Package":"8-SO","Gate Charge (Qg) (Max) @ Vgs":"57 nC @ 10 V","Drain to Source Voltage (Vdss)":"30 V","Input Capacitance (Ciss) (Max) @ Vds":"1200 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"4.5V, 10V","Current - Continuous Drain (Id) @ 25°C":"8.5A (Ta)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d5e9b48483f8486f25733ecfbf3a9e12.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a direct replacement for IRF7403TR?","answer":"Infineon has not assigned an official direct replacement. For new designs, select a current-production N-channel MOSFET in the same SOIC-8 package with 30 V Vdss and 8.5 A or higher Id rating. No single pin-compatible alternate is documented by the manufacturer."},{"question":"Can I use IRF7403PBF instead of IRF7403TR?","answer":"The IRF7403PBF is the lead-free (PbF) version of the same die in the same SOIC-8 package. Electrically they are identical. The TR suffix indicates Tape & Reel packaging; the PBF suffix indicates lead-free plating. If your BOM calls for the TR reel quantity, verify the PBF variant's packaging option — it may ship in tube or different reel count."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRF7403TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRF7403TR when reusing this data.
