For rework and repair scenarios, the through-hole format is far easier to replace than a surface-mount D²PAK — a soldering iron and a desoldering wick are enough, no hot-air station required. No second-source alternate is recorded in the available documentation, so the BOM depends on this single ST order code.","metaTitle":"STP23NM50N N-Channel MOSFET, 500V, 17A, MDmesh II TO-220","metaDescription":"STP23NM50N N-channel 500V MOSFET from STMicroelectronics MDmesh II series. 190mOhm Rds(on), 17A continuous drain, 125W dissipation.","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","Product Status":"Active","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4V @ 250µA","Base Product Number":"STP23","Operating Temperature":"150°C(TJ)","Rds On (Max) @ Id, Vgs":"190mOhm @ 8.5A, 10V","Power Dissipation (Max)":"125W (Tc)","Supplier Device Package":"TO-220","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":"$5.3000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74be461682f34d47772492a7027a8fd3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP23NM50N/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of STP23NM50N?","answer":"The maximum on-resistance is 190 mOhm at 8.5 A drain current with 10 V gate drive.
