The input capacitance is 310 pF at 25 V drain-source. That means the factory has stopped production and no further last-time-buy windows are open. Any procurement for this order code goes through the independent surplus and broker channel. Availability is limited to whatever inventory exists in distribution — once that stock is consumed, the part is gone. For a production BOM that still calls out this exact number, the only path is sourcing verified, date-code-controlled inventory through an independent distributor.","metaTitle":"STD4NK50ZD N-Channel MOSFET, 500V 3A DPAK, Obsolete","metaDescription":"STD4NK50ZD N-Channel MOSFET from STMicroelectronics SuperMESH series. 500V Vdss, 3A Id, 2.7 Ohm Rds(on), DPAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH™","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Vgs (Max)":"±30V","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":"4.5V @ 50µA","Base Product Number":"STD4N","Operating Temperature":"-55°C~150°C(TJ)","Rds On (Max) @ Id, Vgs":"2.7Ohm @ 1.5A, 10V","Power Dissipation (Max)":"45W (Tc)","Supplier Device Package":"DPAK","Gate Charge (Qg) (Max) @ Vgs":"12 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"310 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"3A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/819e551dad59ed14f06c062061088b21.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD4NK50ZD/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD4NK50ZD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD4NK50ZD when reusing this data.
