At 1 A continuous drain, expect roughly 9 W dissipation from the channel alone, which against the 63 W package limit at case temperature leaves thermal headroom for a modest heatsink in still air. ## Active lifecycle — stable supply for production This makes the part a reliable choice for production BOMs where long-term availability matters.","metaTitle":"STMicroelectronics STFW3N150 N-Channel MOSFET, 1500 V, 2.5 A","metaDescription":"STFW3N150 PowerMESH N-channel MOSFET: 1500 V drain-source, 2.5 A continuous, 9 ohm Rds(on) in TO-3P-3 Full Pack.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"PowerMESH™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-3P-3 Full Pack","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 250µA","Base Product Number":"STFW3","Operating Temperature":"150°C (TJ)","Rds On (Max) @ Id, Vgs":"9Ohm @ 1.3A, 10V","Power Dissipation (Max)":"63W (Tc)","Supplier Device Package":"TO-3PF","Gate Charge (Qg) (Max) @ Vgs":"29.3 nC @ 10 V","Drain to Source Voltage (Vdss)":"1500 V","Input Capacitance (Ciss) (Max) @ Vds":"939 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"2.5A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/915bff357004759200fa000a390948f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the STFW3N150 replace the STW3N150?","answer":"The STFW3N150 and STW3N150 share the same die and electrical ratings — 1500 V drain-source, 2.5 A continuous drain, 9 ohm Rds(on). The difference is the package: the STFW3N150 uses the fully isolated TO-3PF (TO-3P Full Pack), while the STW3N150 uses the standard TO-247 with an electrically active tab. They are not pin-compatible; the package footprint and mounting differ. Choose the STFW3N150 when you need the isolated tab for simplified heatsinking."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STFW3N150","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STFW3N150 when reusing this data.
