Independent distributors hold remaining inventory from last-time-buy cycles and excess stock. No direct factory or authorized-distributor pipeline remains. ## Thermal and switching budget for the TO-220 build The TO-220-3 through-hole package is rated for 150 W power dissipation at the case. The 4 V typical gate-threshold at 250 µA is a standard logic-level threshold; the drive voltage for minimum Rds(on) is 10 V, so a 12 V or 15 V gate rail is the right choice for lowest conduction loss.","metaTitle":"STP90N55F4 N-Channel MOSFET, 55V 90A, TO-220-3","metaDescription":"STP90N55F4 DeepGATE™/STripFET™ N-Channel MOSFET, 55V Vdss, 90A Id, 8mOhm Rds(on) at 10V, TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"DeepGATE™, STripFET™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±20V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STP90","Operating Temperature":"-55°C~175°C(TJ)","Rds On (Max) @ Id, Vgs":"8mOhm @ 45A, 10V","Power Dissipation (Max)":"150W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"90 nC @ 10 V","Drain to Source Voltage (Vdss)":"55 V","Input Capacitance (Ciss) (Max) @ Vds":"4800 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"90A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP90N55F4/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of STP90N55F4?","answer":"It comes in a TO-220-3 through-hole package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP90N55F4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP90N55F4 when reusing this data.
