For sustainment of existing designs, the remaining channel is surplus and broker inventory. Any new design-in should target a current-production MDmesh™ or equivalent 500 V N-channel MOSFET in DPAK. The 500 V, 12 A, 320 mOhm rating bracket is well-served by several active alternatives, though pin-compatibility and gate-drive requirements must be verified per the target datasheet. The 500 V drain-source voltage sets the part for offline flyback, forward, and PFC stages operating from rectified 230 VAC or universal input.","metaTitle":"STD14NM50N N-Channel MOSFET, 500 V, 12 A, MDmesh™ II","metaDescription":"STD14NM50N N-Channel MOSFET from STMicroelectronics MDmesh™ II series. 500 V drain-source, 12 A continuous, 320 mOhm Rds(on), DPAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"MDmesh™ II","Package":"Tape & Reel (TR)","FET Type":"N-Channel","Vgs (Max)":"±25V","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":"4V @ 100µA","Base Product Number":"STD14","Operating Temperature":"150°C (TJ)","Rds On (Max) @ Id, Vgs":"320mOhm @ 6A, 10V","Power Dissipation (Max)":"90W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"27 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"816 pF @ 50 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"12A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/29ab57758aac31ee47ab8f069e3eb2c0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD14NM50N/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STD14NM50N?","answer":"STMicroelectronics has not published a direct pin-compatible successor for the STD14NM50N under the MDmesh™ II series. Several active 500 V, 12 A class N-channel MOSFETs in DPAK exist from ST and other vendors, but each has its own gate charge, Rds(on), and switching profile. The replacement choice depends on the specific drive voltage and switching frequency of the application. Cross-reference the gate charge and on-resistance against the original design's margin before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD14NM50N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD14NM50N when reusing this data.
