The 16.5 nC total gate charge (at 10 V) keeps switching losses manageable in hard-switched topologies — a 100 kHz flyback driving this gate from a 10 V supply draws roughly 16.5 mA average from the driver, well within a standard MOSFET driver's capability. Input capacitance is 450 pF typical at 100 V drain-source bias. That low Ciss means the gate driver does not need to push much current during the Miller plateau, which helps keep turn-on and turn-off edges clean without excessive ringing. ## Active production, ROHS3, and sourcing posture No official second-source cross-reference is listed in the ST portfolio for this exact order code.","metaTitle":"STF8N80K5 N-Channel 800 V MOSFET, 6 A, 950 mOhm, TO-220FP","metaDescription":"STF8N80K5 N-channel 800 V MOSFET from STMicroelectronics SuperMESH5 series. 6 A continuous drain, 950 mOhm Rds(on), TO-220FP package.","metaKeywords":null},"attributes":{"series":"SuperMESH5™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH5™","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":"5V @ 100µA","Base Product Number":"STF8","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"950mOhm @ 3A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"16.5 nC @ 10 V","Drain to Source Voltage (Vdss)":"800 V","Input Capacitance (Ciss) (Max) @ Vds":"450 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"6A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5800","priceTiers":[{"qty":1,"price":"$2.58000","currency":"USD"},{"qty":10,"price":"$2.14400","currency":"USD"},{"qty":100,"price":"$1.70640","currency":"USD"},{"qty":500,"price":"$1.44386","currency":"USD"},{"qty":1000,"price":"$1.22509","currency":"USD"},{"qty":2000,"price":"$1.16384","currency":"USD"},{"qty":5000,"price":"$1.12008","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1b6757bef9b553ee051594e6faf05b8b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF8N80K5/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STF8N80K5 in this component family?","answer":"No official pin-compatible alternative or cross-reference is listed by STMicroelectronics for this exact order code.
