The drive voltage range (2.7 V minimum for full enhancement) lets it operate from 3.3 V logic rails without a gate-drive booster, though the 48 nC gate charge still needs a driver capable of sourcing that peak current for fast edges. ## Lifecycle — obsolete, last-time-buy closed Procurement must source through independent distribution — surplus inventory, NOS (new old stock), or broker channels.","metaTitle":"IRF7401TRPBF N-Channel MOSFET, 20 V, 22 mOhm, HEXFET","metaDescription":"IRF7401TRPBF N-Channel MOSFET from Infineon's HEXFET series. 20 V Vdss, 22 mOhm Rds(on) at 4.5 V, 8.7 A continuous drain, -55°C to 150°C TJ.","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); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±12V","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":"700mV @ 250µA (Min)","Base Product Number":"IRF7401","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"22mOhm @ 4.1A, 4.5V","Power Dissipation (Max)":"2.5W (Ta)","Supplier Device Package":"8-SO","Gate Charge (Qg) (Max) @ Vgs":"48 nC @ 4.5 V","Drain to Source Voltage (Vdss)":"20 V","Input Capacitance (Ciss) (Max) @ Vds":"1600 pF @ 15 V","Drive Voltage (Max Rds On, Min Rds On)":"2.7V, 4.5V","Current - Continuous Drain (Id) @ 25°C":"8.7A (Ta)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a2e525544ec4cdfe6b26d8f5f4b0aa52.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IRF7401TRPBF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy IRF7401TRPBF?","answer":"The IRF7401TRPBF is obsolete and no longer available through Infineon's factory channel."},{"question":"Is IRF7401TRPBF obsolete?","answer":"Yes, Infineon has listed the IRF7401TRPBF as obsolete.
