The 900 V drain-source rating gives you a solid 2× derating margin on a typical 400 V rail, which matters when the line rings during a surge. ## Conduction and switching costs Rds(on) is 4.8 Ohms maximum at 1.5 A with 10 V gate drive. That is not a low-Rds(on) part — it is a high-voltage device where the die is sized for breakdown, not for minimal resistance. The TO-220 Full Pack package (TO-220FP) has a fully isolated metal tab — no extra insulating washer needed, which speeds up assembly and reduces thermal interface variability. The through-hole mounting suits point-to-point wiring on prototype boards and production runs where vibration resistance matters. The base product number is STP3NK90, and the 'Z' suffix designates the SuperMESH generation.","metaTitle":"STP3NK90ZFP N-Channel MOSFET, 900 V, 3 A, TO-220FP","metaDescription":"STMicroelectronics STP3NK90ZFP N-channel MOSFET, 900 Vdss, 3 A continuous drain, 4.8 Ohm Rds(on), SuperMESH series, TO-220FP package, -55 to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH™","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":"STP3NK90","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"4.8Ohm @ 1.5A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"22.7 nC @ 10 V","Drain to Source Voltage (Vdss)":"900 V","Input Capacitance (Ciss) (Max) @ Vds":"590 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"3A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2f2eb14a05fb99884ab450844a2d845f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP3NK90ZFP/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum drain current of STP3NK90ZFP?","answer":"The continuous drain current is 3 A at 25°C case temperature.
