It is designed for offline flyback converters, PFC stages, and auxiliary power supplies where the primary switch sees a reflected voltage plus a safety margin. ## Gate charge and switching — 13 nC keeps the driver happy Input capacitance measures 385 pF at 25 V drain-source. ## TO-220FP full pack — no insulating washer needed The through-hole TO-220FP package has a fully molded plastic body with no exposed metal tab. That means the heatsink interface does not require an insulating pad or mica washer — the back of the package is already isolated. The trade-off is higher thermal resistance than a standard TO-220 with a metal tab; the 20 W maximum dissipation at the case assumes a good thermal bond to a heatsink. If the board runs in a confined enclosure, budget for a clip-on heatsink or a larger pad area on the PCB. ## Active lifecycle — no LTB concern for production ST lists the STF3N62K3 as Active.","metaTitle":"STF3N62K3 N-Channel MOSFET, 620 V, 2.7 A, TO-220FP","metaDescription":"STF3N62K3 N-Channel MOSFET from STMicroelectronics SuperMESH3™ series. 620 V Vdss, 2.7 A continuous drain, 2.5 Ω Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH3™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STF3N62","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"2.5Ohm @ 1.4A, 10V","Power Dissipation (Max)":"20W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"13 nC @ 10 V","Drain to Source Voltage (Vdss)":"620 V","Input Capacitance (Ciss) (Max) @ Vds":"385 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"2.7A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2645123347a419296b7030d1ccb21663.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF3N62K3/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF3N62K3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF3N62K3 when reusing this data.
