Compared to the HCPL0637R2 (5 kV/µs CMTI), this part offers 5× the transient immunity, which is the deciding factor when the optocoupler sits on a 600V switching node; the HCPL0638R2 sits in between at 10 kV/µs.","metaTitle":"HCPL0639R2 onsemi Optoisolator – 10 Mbps, 25 kV/µs, 8-SOIC","metaDescription":"onsemi HCPL0639R2 dual-channel optocoupler: 10 Mbps data rate, 25 kV/µs CMTI, open-collector Schottky-clamped output, 3750 Vrms isolation, -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Data Rate":"10Mbps","Input Type":"DC","Output Type":"Open Collector, Schottky Clamped","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"2","Base Product Number":"HCPL0639","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 85°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"17ns, 5ns","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Forward (Vf) (Typ)":"1.75V (Max)","Current - DC Forward (If) (Max)":"-","Propagation Delay tpLH / tpHL (Max)":"75ns, 75ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1500","priceTiers":[{"qty":1,"price":"$6.15000","currency":"USD"},{"qty":10,"price":"$4.34900","currency":"USD"},{"qty":100,"price":"$3.56180","currency":"USD"},{"qty":500,"price":"$3.00266","currency":"USD"},{"qty":1000,"price":"$2.75417","currency":"USD"},{"qty":2500,"price":"$2.64027","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d87989943ba65496217d84f8b6494a2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/HCPL0639R2/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between HCPL0639 and HCPL0639R2?","answer":"The electrical specs are identical — 10 Mbps, 25 kV/µs CMTI, same pinout.
