The 8.5 Ohm maximum on-resistance at 900 mA and 10 V gate drive sets the conduction loss floor for auxiliary supply rails, flyback clamp circuits, and high-voltage DC-DC stages where the load current stays under 1 A continuous. ## Gate drive and switching budget Total gate charge is 16 nC at 10 V, which means a standard gate-drive IC or a discrete driver stage can switch this FET at moderate frequencies without excessive drive current. Input capacitance is 499 pF at 25 V drain-source — the Miller plateau is manageable, but the layout should keep the gate loop tight to avoid ringing on the 1000 V rail. ## Temperature grade and package reality The IPAK (TO-251AA) through-hole package with short leads needs the PCB hole pattern matched to the TO-251AA land footprint — the three leads are not the standard TO-220 pitch, so verify the board layout before committing.","metaTitle":"STU2NK100Z N-Channel 1000V MOSFET, SuperMESH™, IPAK","metaDescription":"STMicroelectronics STU2NK100Z N-channel 1000V 1.85A MOSFET in IPAK. 8.5 Ohm Rds(on) at 10V, 16 nC gate charge, -55 to 150°C.","metaKeywords":null},"attributes":{"series":"SuperMESH™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"SuperMESH™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Through Hole","Package / Case":"TO-251-3 Short Leads, IPak, TO-251AA","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"8.5Ohm @ 900mA, 10V","Power Dissipation (Max)":"70W (Tc)","Supplier Device Package":"IPAK","Gate Charge (Qg) (Max) @ Vgs":"16 nC @ 10 V","Drain to Source Voltage (Vdss)":"1000 V","Input Capacitance (Ciss) (Max) @ Vds":"499 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"1.85A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.23000","currency":"USD"},{"qty":75,"price":"$2.56133","currency":"USD"},{"qty":150,"price":"$2.19540","currency":"USD"},{"qty":525,"price":"$1.95149","currency":"USD"},{"qty":1050,"price":"$1.67095","currency":"USD"},{"qty":2025,"price":"$1.57338","currency":"USD"},{"qty":5025,"price":"$1.50950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/89876ab9d08c78e2afd0d8dcd4f60c94.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a direct replacement for STU2NK100Z?","answer":"The part is single-sourced from STMicroelectronics.
