It comes in a TO-220-3 Full Pack through-hole package (TO-220FP), designed for isolated mounting without a separate insulator. The device is now classified as obsolete per ST's product lifecycle. ## Switching and drive characteristics The full-pack package eliminates the need for a mounting pad or thermal compound to ground, simplifying assembly in isolated-supply layouts. ## Temperature range and design margin Maximum power dissipation is 25 W at case temperature, so thermal management through the TO-220FP tab is still required at full load. ## Sourcing reality — obsolete, available through independent channels ST lists the STF11N50M2 as obsolete. For BOM lines that already use this device, the only sourcing path is the independent distribution and spot market.","metaTitle":"STF11N50M2 N-Channel MOSFET, 500V, 530mOhm, TO-220FP","metaDescription":"STF11N50M2 MDmesh II Plus N-Channel MOSFET, 500V Vdss, 8A Id, 530mOhm Rds(on), TO-220FP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ II Plus","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±25V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STF11","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"530mOhm @ 4A, 10V","Power Dissipation (Max)":"25W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"12 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"395 pF @ 100 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"8A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/89e51022a0fde0a5f2362ab328705839.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF11N50M2/alternatives.json"},"ai":{"faq":[{"question":"What is the exact replacement for STF11N50M2?","answer":"No official replacement part number is listed by ST in the available records.
