Gate charge is 20 nC at 5 V, which moderates switching losses in hard-switched topologies. Procurement must source this part through surplus or broker channels.","metaTitle":"STD65N55LF3 N-Channel MOSFET, 55 V, 80 A, DPAK","metaDescription":"STD65N55LF3 N-channel MOSFET from STMicroelectronics STripFET™ III series. 55 V Vdss, 80 A continuous drain, 8.5 mOhm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"STripFET™ III","Package":"Tape & Reel (TR) Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPAK (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"2.5V @ 250µA","Base Product Number":"STD65N","Operating Temperature":"-55°C ~ 175°C (TJ)","Rds On (Max) @ Id, Vgs":"8.5mOhm @ 32A, 10V","Power Dissipation (Max)":"110W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"20 nC @ 5 V","Drain to Source Voltage (Vdss)":"55 V","Input Capacitance (Ciss) (Max) @ Vds":"2200 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"5V, 10V","Current - Continuous Drain (Id) @ 25°C":"80A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d88576eac5d73435dc4b9345955ed12e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD65N55LF3/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for STD65N55LF3?","answer":"No official direct replacement or successor is listed by STMicroelectronics for the STD65N55LF3. For a pin-compatible alternative, look for other N-channel MOSFETs in the DPAK (TO-252) package with similar 55 V Vdss and 80 A current rating from the same or other manufacturers, but verify gate drive and Rds(on) specifications against your design requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD65N55LF3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD65N55LF3 when reusing this data.
