The dual diode schematic printed on the package confirms a common-cathode configuration, integrating two independent fast recovery diodes on a single die — a common design for reducing part count and PCB space in dual-rectification circuits.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis device is part of AUK's SF-series ultrafast recovery diode family, closely related to their SF10A40H (400V, 10A, single diode) datasheet line. Based on this family's characteristics, the SFF1040CT offers a \u003cstrong\u003e400V maximum repetitive reverse voltage\u003c\/strong\u003e with \u003cstrong\u003e10A average forward current per diode\u003c\/strong\u003e, along with fast reverse recovery time for reduced switching losses in high-frequency circuits. It features high voltage reliability, high-speed switching, low power loss, and high efficiency, and is halogen-free and RoHS compliant.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIts isolated TO-220F package simplifies heatsink mounting since no separate insulating mica pad is typically required, while the dual common-cathode configuration makes it well suited for center-tapped rectification, dual-output power supplies, and other applications needing two matched fast recovery diodes in one compact package.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eKey Specifications\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Dual Fast Recovery Rectifier Diode (common cathode)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e AUK Corp\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePackage Marking:\u003c\/strong\u003e SFF1040CT\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e TO-220F (isolated, 3-lead)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMaximum Repetitive Reverse Voltage (VRRM):\u003c\/strong\u003e 400V\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAverage Forward Current (per diode):\u003c\/strong\u003e 10A\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFast reverse recovery time\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHalogen-free, RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eCommon Applications\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSwitch-mode power supplies (SMPS)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFreewheeling diode for motor drive applications\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDC-DC converter systems\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePower factor correction (boost diode)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDual\/center-tapped rectification circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003ePackage Includes\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1 x AUK SFF1040CT Dual Fast Recovery Diode (TO-220F)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"digilog.pk","offers":[{"title":"Default Title","offer_id":51658060431638,"sku":null,"price":150.0,"currency_code":"PKR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0764\/1366\/files\/sff10400ct-dual-fast-recovery-rectifier-diode-10a-400v-to-220f-common-cathode-1.jpg?v=1786809763","url":"https:\/\/digilog.pk\/products\/sff1040ct-dual-fast-recovery-rectifier-diode-10a-400v-to-220f-common-cathode","provider":"digilog.pk","version":"1.0","type":"link"}
