Input capacitance (Ciss) is 1330 pF at 50 V Vds. ## Thermal and mounting — the isolated package advantage Maximum power dissipation is 30 W at case temperature, with the junction rated to 150°C. The TO-220FP body is fully molded — no exposed metal tab — so the device can be mounted directly to a grounded heatsink without an insulating pad. This saves a part and a assembly step, but the plastic package has higher thermal resistance than a standard TO-220 with a metal tab; the thermal design should account for that. The through-hole leads suit wave-solder or hand-solder rework equally well. The base product number is STF23, which covers the TO-220FP variant of the MDmesh II 500 V family.","metaTitle":"STF23NM50N N-Channel MOSFET, 500 V, 17 A, TO-220FP","metaDescription":"STMicroelectronics STF23NM50N N-channel MDmesh II MOSFET, 500 Vdss, 17 A Id, 190 mOhm Rds(on), TO-220FP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ II","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":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STF23","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"190mOhm @ 8.5A, 10V","Power Dissipation (Max)":"30W (Tc)","Supplier Device Package":"TO-220FP","Gate Charge (Qg) (Max) @ Vgs":"45 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"1330 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"17A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74be461682f34d47772492a7027a8fd3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STF23NM50N/alternatives.json"},"ai":{"faq":[{"question":"Is STF23NM50N RoHS compliant?","answer":"The STF23NM50N is a lead-free device from STMicroelectronics.
