Total gate charge is 19 nC at Vgs = 10 V, which keeps the gate drive energy low enough for a simple bootstrap or transformer-coupled driver at switching frequencies up to 100 kHz or so. Input capacitance Ciss is 460 pF at Vds = 25 V. Combined with the 19 nC gate charge, the gate driver load is light.","metaTitle":"STF5N95K3 N-Channel MOSFET, 950V, 4A, TO-220FP","metaDescription":"STF5N95K3 N-channel MOSFET from STMicroelectronics SuperMESH3 series. 950V Vdss, 4A continuous drain, 3.5 Ohm Rds(on).","metaKeywords":null},"attributes":{"series":"SuperMESH3™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"5V @ 100µA","Base Product Number":"STF5N95","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"3.5Ohm @ 2A, 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)":"950 V","Input Capacitance (Ciss) (Max) @ Vds":"460 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"4A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0300","priceTiers":[{"qty":1,"price":"$3.03000","currency":"USD"},{"qty":10,"price":"$2.54300","currency":"USD"},{"qty":100,"price":"$2.05690","currency":"USD"},{"qty":500,"price":"$1.82834","currency":"USD"},{"qty":1000,"price":"$1.56552","currency":"USD"},{"qty":2000,"price":"$1.47410","currency":"USD"},{"qty":5000,"price":"$1.41425","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c78a655001ee852717e11e0cd564a55a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF5N95K3/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of STF5N95K3?","answer":"Actual Rds(on) increases with junction temperature — refer to the normalised curve in the datasheet for your operating point."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF5N95K3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF5N95K3 when reusing this data.
