With a DC input and transistor output, it couples logic-level signals across the isolation boundary, making it a fit for PLC digital inputs, motor-drive feedback, and isolated communication interfaces where the 5000Vrms withstand voltage provides the creepage and clearance margin for reinforced insulation per IEC 60950-1. A 19% floor means the output transistor can sink at least 3 mA from a 20V rail when the LED is driven at 16 mA, which is sufficient to pull a standard TTL or CMOS input low through a pull-up resistor. Turn-on and turn-off times are 250 ns and 260 ns typical respectively — the combined propagation delay of roughly half a microsecond sets the upper data rate at about 1 Mbps before pulse-width distortion becomes significant. For isolated serial buses like RS-485 or CAN at 250 kbps, this margin is comfortable. ## Industrial temperature range and surface-mount assembly The 8-SMD Gull Wing package (supplier device package 8-SMD) is a surface-mount form factor compatible with standard reflow soldering profiles. The Gull Wing leads provide visual solder-joint inspection access and relieve mechanical stress between the package body and the board during thermal cycling.","metaTitle":"onsemi HCPL2531TSVM Optoisolator, 5000Vrms, 2-Ch","metaDescription":"onsemi HCPL2531TSVM dual-channel transistor output optocoupler, 5000Vrms isolation, 19-50% CTR at 16mA, 250ns switching, -40°C to 100°C, 8-SMD Gull Wing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Bulk","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"8-SMD, Gull Wing","Product Status":"Active","lifecycle_stage":"eol_hot","Number of Channels":"2","Base Product Number":"HCPL2531","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"-","Operating Temperature":"-40°C~100°C","Rise / Fall Time (Typ)":"-","Voltage - Output (Max)":"20V","Supplier Device Package":"8-SMD","Current - Output / Channel":"8mA","Current Transfer Ratio (Max)":"50% @ 16mA","Current Transfer Ratio (Min)":"19% @ 16mA","Voltage - Forward (Vf) (Typ)":"1.45V","Turn On / Turn Off Time (Typ)":"250ns, 260ns","Current - DC Forward (If) (Max)":"25 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3517","priceTiers":[{"qty":232,"price":"$1.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/16dc349f4c8975de52e11cd5e2ec17fd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HCPL2531TSVM/alternatives.json"},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) range for HCPL2531TSVM?","answer":"The CTR is 19% minimum to 50% maximum at a forward current of 16 mA.
