It is designed for isolated digital signal transmission in industrial control, motor drives, PLC I/O modules, and isolated power-supply feedback paths where galvanic isolation is required between logic domains. ## 10 Mbps with 75 ns propagation delay — enough margin for most isolated SPI and UART links The 10 Mbps data rate with a maximum propagation delay of 75 ns (tpLH / tpHL) is sufficient for isolated SPI at 5 MHz clock, isolated UART at standard baud rates up to 1 Mbps, and industrial fieldbus interfaces like RS-485 or CAN when used with an external transceiver. The 75 ns delay is symmetrical, which simplifies timing closure in bidirectional links. Rise and fall times of 20 ns and 5 ns typical keep the output edges clean enough for most logic families without excessive ringing, though a small series resistor at the output is still recommended to damp reflections on long traces. ## 15 kV/µs CMTI — why it matters for motor-drive and switching-power-supply isolation Common-mode transient immunity of 15 kV/µs (minimum) means this optocoupler can reject the fast voltage slew rates present on the switching node of a motor-drive IGBT or a high-frequency power converter. A lower CMTI part would glitch or latch up under those conditions, causing false data or even output oscillation. This spec is the difference between a design that passes EMC testing and one that fails on the first motor start. ## Open-collector output — flexible level shifting, but budget the pull-up The trade-off is that an external pull-up resistor must be added per channel — factor that into the BOM count and board area.","metaTitle":"PS9817A-2-F3-AX NEPOC Optocoupler, 10 Mbps","metaDescription":"PS9817A-2-F3-AX NEPOC optocoupler: 10 Mbps data rate, 2500 Vrms isolation, 2 open-collector channels, 15 kV/µs CMTI, -40°C to 85°C, 8-SSOP.","metaKeywords":null},"attributes":{"series":"NEPOC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"NEPOC","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"10Mbps","Input Type":"DC","Output Type":"Open Collector","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 85°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"20ns, 5ns","Supplier Device Package":"8-SSOP","Current - Output / Channel":"25 mA","Voltage - Forward (Vf) (Typ)":"1.65V","Current - DC Forward (If) (Max)":"15mA","Propagation Delay tpLH / tpHL (Max)":"75ns, 75ns","Common Mode Transient Immunity (Min)":"15kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.31000","currency":"USD"},{"qty":1500,"price":"$2.67200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1c7aa1cea8a302fcf8678d46a471b812.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of the PS9817A-2-F3-AX?","answer":"The PS9817A-2-F3-AX is rated for a data rate of 10 Mbps, with a maximum propagation delay of 75 ns (both tpLH and tpHL).
