Its headline rating is 5000Vrms galvanic isolation, backed by a minimum common-mode transient immunity of 15kV/µs — the spec that keeps the data path clean when a motor drive or inverter switches a high-voltage rail. The 10Mbps data rate covers most industrial fieldbus links (Profibus, DeviceNet, RS-485 isolators), and the open-collector output lets you wire-OR multiple signals or translate from 5V logic down to a lower-voltage controller. Supply range is 4.5V to 5.5V on the output side; the input LED forward voltage is 1.65V typical, with a max forward current of 30mA. ## Open collector vs push-pull — why it matters for the BOM An open-collector output requires an external pull-up resistor to Vcc (typically 1kΩ to 10kΩ, depending on bus capacitance and speed). That pull-up adds two passives to the BOM, but it also buys flexibility: you can pull up to a different voltage than the optocoupler's own supply, level-shifting the output to 3.3V or 2.5V logic. The trade-off is slower rise time compared to a push-pull (totem-pole) output, which has a dedicated high-side driver. The PS9587L1-AX's typical rise/fall times of 20ns and 10ns are fast enough for 10Mbps signalling; the 75ns max propagation delay (tpLH/tpHL) sets the timing budget for the loop. ## Through-hole 8-DIP — shelf life and storage The PS9587L1-AX comes in a through-hole 8-DIP package (0.400\" body width, 10.16mm pitch). No moisture sensitivity level (MSL) is listed for DIP packages — they are generally not moisture-sensitive, so no bake is needed before reflow or wave soldering.","metaTitle":"PS9587L1-AX NEPOC Optocoupler, 10Mbps, Open Collector","metaDescription":"PS9587L1-AX NEPOC optocoupler: 10Mbps data rate, open collector output, 5000Vrms isolation, 15kV/µs CMTI, -40°C to 85°C, 8-DIP through hole.","metaKeywords":null},"attributes":{"series":"NEPOC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"NEPOC","Package":"Tube","Data Rate":"10Mbps","Input Type":"DC","Output Type":"Open Collector","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.400\\\", 10.16mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 85°C","Inputs - Side 1/Side 2":"1/0","Rise / Fall Time (Typ)":"20ns, 10ns","Supplier Device Package":"8-DIP","Current - Output / Channel":"25 mA","Voltage - Forward (Vf) (Typ)":"1.65V","Current - DC Forward (If) (Max)":"30mA","Propagation Delay tpLH / tpHL (Max)":"75ns, 75ns","Common Mode Transient Immunity (Min)":"15kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.95000","currency":"USD"},{"qty":10,"price":"$3.50000","currency":"USD"},{"qty":100,"price":"$2.86640","currency":"USD"},{"qty":500,"price":"$2.41642","currency":"USD"},{"qty":1000,"price":"$2.21644","currency":"USD"},{"qty":2000,"price":"$2.12479","currency":"USD"}]},"links":{"datasheetUrl":"https://www.renesas.com/us/en/oauth2/default/v1/authorize?client_id=0oa2ixjskq8o2hdJB357&response_type=code&scope=openid%20email%20phone%20profile%20MyRenesasUserInfo&redirect_uri=https%3A//www.renesas.com/openid-connect/renesas-okta&state=gD2NBkRXIQLp2h0","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between open collector and push-pull output in optocouplers?","answer":"An open-collector output (like the PS9587L1-AX) requires an external pull-up resistor and can only pull the output low; it cannot drive high actively. This allows wired-OR connections and level translation to a different supply voltage. A push-pull output has both high-side and low-side drivers, giving faster rise times and no external resistor, but it cannot be wire-ORed and is tied to the same supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/PS9587L1-AX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/PS9587L1-AX when reusing this data.
