Gate charge totals 19 nC at 10 V. Input capacitance is 547 pF at 50 V drain-source. That keeps the Miller plateau narrow and the switching edges clean enough for most offline converters without aggressive gate resistors.","metaTitle":"STF11NM50N N-Channel MOSFET, 500V 8.5A TO-220FP","metaDescription":"STF11NM50N N-channel 500V 8.5A MOSFET in TO-220FP full-pack. 470mOhm Rds(on), 19nC gate charge.","metaKeywords":null},"attributes":{"series":"MDmesh™ II","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ II","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±25V","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":"4V @ 250µA","Base Product Number":"STF11","Operating Temperature":"150°C (TJ)","Rds On (Max) @ Id, Vgs":"470mOhm @ 4.5A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"19 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"547 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"8.5A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4768","priceTiers":[{"qty":1,"price":"$3.00000","currency":"USD"},{"qty":10,"price":"$2.69300","currency":"USD"},{"qty":100,"price":"$2.20610","currency":"USD"},{"qty":500,"price":"$1.87802","currency":"USD"},{"qty":1000,"price":"$1.86778","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/483426d3a041366a3b490cd733c9e7b5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF11NM50N/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STF11NM50N in the MDmesh II family?","answer":"Within the same MDmesh II series, the STF11NM50N is the base 500 V, 8.5 A variant.
