These numbers tell you the gate driver needs to source about 28 nC per switching cycle — manageable with a standard gate-drive IC or a discrete totem-pole. The ±30 V maximum gate-source rating gives some headroom against ringing on long gate traces, but keep the layout tight to avoid exceeding it during hard switching.","metaTitle":"STD5NK50Z-1 N-Channel MOSFET, 500V, 4.4A, TO-251 IPak","metaDescription":"STD5NK50Z-1 N-channel SuperMESH MOSFET, 500V Vdss, 4.4A Id, 1.5 Ohm Rds(on), TO-251 IPak.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-251-3 Short Leads, IPak, TO-251AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STD5N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"1.5Ohm @ 2.2A, 10V","Power Dissipation (Max)":"70W (Tc)","Supplier Device Package":"I-PAK","Gate Charge (Qg) (Max) @ Vgs":"28 nC @ 10 V","Drain to Source Voltage (Vdss)":"500 V","Input Capacitance (Ciss) (Max) @ Vds":"535 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"4.4A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b86a4aba2b541fe23c0e999d2fbe7295.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STD5NK50Z-1/alternatives.json"},"ai":{"faq":[{"question":"Is STD5NK50Z-1 obsolete and still available for purchase?","answer":"Yes, STD5NK50Z-1 is listed as Obsolete by STMicroelectronics.

For new designs, select a current-production 500 V N-channel MOSFET in a TO-251 or surface-mount DPAK package with similar Rds(on) and gate charge. Cross-reference against ST's current SuperMESH or MDmesh families, but verify pin compatibility and thermal performance for your specific application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD5NK50Z-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD5NK50Z-1 when reusing this data.
