With a total gate charge of 15.5 nC at 10 V and input capacitance of 350 pF at 50 V drain-source, this MOSFET switches fast enough for a typical 50–100 kHz LED driver without excessive gate-drive losses. The 4.5 V threshold at 50 µA means it's fully enhanced with a standard 10 V gate drive; a logic-level 5 V signal won't reliably turn it on hard — budget a gate-driver IC or a bootstrap rail if your controller output is 5 V only.","metaTitle":"STMicroelectronics STDLED623 N-Channel MOSFET, 620 V, 3 A","metaDescription":"STMicroelectronics STDLED623 N-Channel MOSFET, 620 Vds, 3 A continuous drain, 3.6 Ohm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tape & Reel (TR)","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STDLED623","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"3.6Ohm @ 1.1A, 10V","Power Dissipation (Max)":"45W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"15.5 nC @ 10 V","Drain to Source Voltage (Vdss)":"620 V","Input Capacitance (Ciss) (Max) @ Vds":"350 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"3A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/229821ad76120ad217abd35998ab0a1c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STDLED623/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STDLED623","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STDLED623 when reusing this data.
