This is the figure to budget for conduction loss in the steady-state — at 4.5 A the I²R loss is about 10.5 W, which must be within the 125 W power dissipation limit and the thermal capability of the board copper and heatsinking. Gate charge totals 68 nC at 10 V. The input capacitance is 1390 pF at 25 V drain-source — this sets the switching energy per cycle and influences the driver's peak current requirement. The gate threshold voltage is specified at 4.5 V maximum with 100 µA drain current. It is ROHS3 compliant.","metaTitle":"STB11NK50ZT4 MOSFET N-CH 500V 10A D2PAK, 520mOhm Rds(on)","metaDescription":"STB11NK50ZT4 N-channel 500V 10A MOSFET in D2PAK. 520mOhm Rds(on) at 10V gate drive, 68 nC gate charge.","metaKeywords":null},"attributes":{"series":"SuperMESH™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"SuperMESH™","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 100µA","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"520mOhm @ 4.5A, 10V","Power Dissipation (Max)":"125W (Tc)","Supplier Device Package":"D2PAK","Gate Charge (Qg) (Max) @ Vgs":"68 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"1390 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"10A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1","priceTiers":[{"qty":1,"price":"$3.25000","currency":"USD"},{"qty":10,"price":"$2.91800","currency":"USD"},{"qty":100,"price":"$2.39110","currency":"USD"},{"qty":500,"price":"$2.03550","currency":"USD"},{"qty":1000,"price":"$2.02440","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/19105b188cead8573eaefbbf38d47623.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STB11NK50ZT4/alternatives.json"},"ai":{"faq":[{"question":"What is the STB11NK50ZT4 Rds(on) value?","answer":"This is the conduction loss figure to use for thermal budgeting in a switching converter or motor drive."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STB11NK50ZT4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STB11NK50ZT4 when reusing this data.
