It provides 2500 Vrms galvanic isolation between input and output sides, with a common-mode transient immunity of 10 kV/µs — enough to reject fast switching edges in motor-drive or inverter environments. The 60 ns max propagation delay keeps timing margins tight for isolated SPI, CAN, or encoder interfaces. ## Dual-channel vs single-channel: which NEPOC optocoupler fits? The PS9851-2-F3-AX is the dual-channel variant in the PS9851 family. Its single-channel sibling, the PS9851-1-F3-AX, shares the same 15 Mbps data rate, push-pull output, and 2500 Vrms isolation, but in a single-channel 8-pin package. If the design needs two isolated digital paths — say, TX and RX for an isolated UART — the dual-channel part saves board space and per-channel cost versus using two single-channel devices. The PS9821-2-F3-AX is a dual-channel NEPOC part with open-collector output (25 mA sink) and slightly slower 75 ns propagation delay, better suited for driving relays or optocoupler inputs rather than high-speed digital buses. ## Active lifecycle, ROHS3, and sourcing posture It is a current-production part from Renesas's NEPOC series, available through independent distribution.","metaTitle":"PS9851-2-F3-AX Renesas NEPOC Optocoupler, 15Mbps, 2500Vrms","metaDescription":"Renesas PS9851-2-F3-AX NEPOC optocoupler: 15 Mbps data rate, 2500 Vrms isolation, push-pull output, 2 channels, 8-SSOP, -40°C to 100°C.","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":"15Mbps","Input Type":"DC","Output Type":"Push-Pull, Totem Pole","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 ~ 100°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"4ns, 4ns","Supplier Device Package":"8-SSOP","Current - Output / Channel":"2 mA","Voltage - Forward (Vf) (Typ)":"1.6V","Current - DC Forward (If) (Max)":"20mA","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"10kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.87","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.87000","currency":"USD"},{"qty":10,"price":"$4.85700","currency":"USD"},{"qty":100,"price":"$3.97820","currency":"USD"},{"qty":500,"price":"$3.35370","currency":"USD"},{"qty":1500,"price":"$3.07616","currency":"USD"},{"qty":3000,"price":"$2.94895","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/141eef12d60591abfd9e6f43673b48c1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is PS9851-2-F3-AX obsolete or end-of-life?","answer":"No."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS9851-2-F3-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS9851-2-F3-AX when reusing this data.
