Its 950 V drain-source rating (Vdss) suits offline power-conversion applications. The 7.5 A continuous drain current is specified at 25°C case temperature; above 100°C junction the current must be derated per the datasheet's SOA curve, and the 30 W power dissipation ceiling becomes the binding constraint in a real enclosure. ## Gate drive and switching parasitics Gate charge totals 30 nC at 10 V drive — modest for a 950 V device, which keeps the driver burden low in a 100 kHz hard-switched converter. Input capacitance is 855 pF at 10 V drain bias; the switching speed is set by the gate-drive source impedance and the external gate resistor. The ±30 V Vgs max gives headroom for gate-drive overshoot during fast turn-on edges. ST lists the STFI15N95K5 as obsolete.","metaTitle":"STFI15N95K5 N-Channel MOSFET, 950 V, 7.5 A, MDmesh K5","metaDescription":"STMicroelectronics STFI15N95K5 N-channel MOSFET, 950 V Vdss, 7.5 A Id, 500 mOhm Rds(on).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ K5","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Full Pack, I²Pak","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"5V @ 100µA","Base Product Number":"STFI15N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"500mOhm @ 5.5A, 10V","Power Dissipation (Max)":"30W","Supplier Device Package":"I2PAKFP (TO-281)","Gate Charge (Qg) (Max) @ Vgs":"30 nC @ 10 V","Drain to Source Voltage (Vdss)":"950 V","Input Capacitance (Ciss) (Max) @ Vds":"855 pF @ 10 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"7.5A (Ta)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is STFI15N95K5 obsolete?","answer":"Yes, STMicroelectronics lists the STFI15N95K5 as obsolete."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STFI15N95K5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STFI15N95K5 when reusing this data.
