It consists of a Gallium Arsenide infrared emitting LED optically coupled to a silicon NPN phototransistor, providing electrical isolation between input and output circuits while still allowing signal transfer — a fundamental building block for isolating control signals from power circuits.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eHoused in the industry-standard \u003cstrong\u003eDIP-6\u003c\/strong\u003e package, the K4N26 interfaces easily with common logic families and is widely used wherever electrical isolation between two circuits is needed, without an isolation test voltage typically in the 5000VRMS range for this device family. The phototransistor output includes a base connection, giving designers added flexibility to adjust switching speed and sensitivity in the output stage if needed.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis type of optocoupler is a staple in power electronics and control circuit design, commonly used for AC mains detection, reed relay driving, switch-mode power supply feedback isolation, logic ground isolation, and general signal isolation between high-voltage and low-voltage sections of a circuit.\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 Single-channel phototransistor optocoupler (with base connection)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Everlight Electronics\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e DIP-6 (through-hole)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIsolation Voltage:\u003c\/strong\u003e ~5000VRMS (typical for 4N26 family)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e Gallium Arsenide Infrared LED\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e Silicon NPN phototransistor\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInterfaces with common logic families\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLow input-output coupling capacitance for noise rejection\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\"\u003eAC mains detection\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReed relay driving\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSwitch-mode power supply (SMPS) feedback isolation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLogic ground isolation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTelephone ring detection\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGeneral signal isolation between high-voltage and low-voltage 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 Everlight K4N26 Optocoupler (DIP-6)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"digilog.pk","offers":[{"title":"Default Title","offer_id":51657909469462,"sku":null,"price":0.0,"currency_code":"PKR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0764\/1366\/files\/4N26PhototransistorOptocouplerDIP-6USED.jpg?v=1786103291","url":"https:\/\/digilog.pk\/products\/4n26-phototransistor-optocoupler-dip-6-used","provider":"digilog.pk","version":"1.0","type":"link"}
