The part is designed for high-voltage switching applications such as off-line power supplies, adapters, and lighting ballasts where the 620 V drain-source breakdown voltage gives adequate derating for universal-input (85–265 VAC) flyback or forward converters. ## Rds(on) and gate drive — 340 mOhm at 10 V Maximum on-resistance is 340 mOhm at a drain current of 7.5 A with 10 V gate drive. Gate charge is 105 nC at 10 V, which is moderate for this voltage class — a gate-drive IC capable of sourcing at least 1 A peak will keep switching losses under control at frequencies up to about 100 kHz. Input capacitance is 3100 pF at 50 V drain-source, a figure to include in the gate-drive power budget. ## Obsolete — no official successor on record Sourcing is limited to independent distribution and surplus inventory — we can quote against an RFQ from our multi-source network. Buyers should verify stock and pricing at the time of inquiry, as availability is batch-dependent.","metaTitle":"STF17N62K3 N-Channel MOSFET, 620 V, 15.5 A, TO-220FP","metaDescription":"STF17N62K3 SuperMESH3 N-channel MOSFET, 620 Vdss, 15.5 A, 340 mOhm Rds(on).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 100µA","Base Product Number":"STF17","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"340mOhm @ 7.5A, 10V","Power Dissipation (Max)":"40W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"105 nC @ 10 V","Drain to Source Voltage (Vdss)":"620 V","Input Capacitance (Ciss) (Max) @ Vds":"3100 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"15.5A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7a09bfa2b09fd6dce7625aed03c5ed81.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use STF17N62K3 as a replacement for STP17N62K3?","answer":"The STP17N62K3 is the standard TO-220 version (non-isolated tab) of the same die. The STF17N62K3 has a fully isolated TO-220FP package, so the electrical ratings are similar, but the thermal resistance and mounting method differ. They are not drop-in replacements — the package footprint and heatsinking approach must be evaluated.
