With a minimum current transfer ratio of 500% at 1.6 mA forward current, the Darlington output stage can drive a logic gate or microcontroller input with less than 2 mA LED drive, keeping the input-side power budget low. Typical turn-on time is 240 ns and turn-off time is 1.3 µs, which limits the usable data rate to roughly 300 kbps in a non-return-to-zero scheme — adequate for isolated RS-232, I²C, or slow SPI links, but not for high-speed CAN or Ethernet. ## Output drive and temperature range ## Production status and package form ## Input characteristics and LED drive The input is a DC-coupled LED with a typical forward voltage of 1.3 V and an absolute maximum forward current of 20 mA, so a series resistor is required when driving from a 3.3 V or 5 V logic output. Because the output is a Darlington pair with the base brought out to pin 6, the user can add a base-emitter resistor to adjust switching speed or tailor the CTR for a specific load — a flexibility not available in standard Darlington optocouplers.","metaTitle":"6N139SVM onsemi Optoisolator – 5000 Vrms, Darlington Output","metaDescription":"onsemi 6N139SVM single-channel optocoupler with 5000 Vrms isolation, 500% min CTR at 1.6 mA, Darlington output with base, -40°C to 100°C, 8-SMD Gull Wing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Bulk","Input Type":"DC","Output Type":"Darlington with Base","Mounting Type":"Surface Mount","Package / Case":"8-SMD, Gull Wing","Product Status":"Active","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"6N139","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"-","Operating Temperature":"-40°C ~ 100°C","Rise / Fall Time (Typ)":"-","Voltage - Output (Max)":"18V","Supplier Device Package":"8-SMD","Current - Output / Channel":"60mA","Current Transfer Ratio (Max)":"-","Current Transfer Ratio (Min)":"500% @ 1.6mA","Voltage - Forward (Vf) (Typ)":"1.3V","Turn On / Turn Off Time (Typ)":"240ns, 1.3µs","Current - DC Forward (If) (Max)":"20 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9500","priceTiers":[{"qty":439,"price":"$0.68000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/646a30e661680f909facce39eb3cee6c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/6N139SVM/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the 6N139 and the 6N139SVM?","answer":"The 6N139SVM is the surface-mount Gull Wing variant of the through-hole 6N139. The electrical specifications — 5000 Vrms isolation, 500% minimum CTR, Darlington output — are identical. The package is the only difference."},{"question":"Can the 6N139SVM be used for 24 V logic-level translation?","answer":"Yes, with a series resistor on the input LED. The output can sink up to 60 mA at 18 V, so it can drive a 24 V logic input through a pull-up resistor to 24 V, provided the collector-emitter voltage does not exceed 18 V. For 24 V rails, a resistor divider or a level-shift transistor on the output side is recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/6N139SVM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/6N139SVM when reusing this data.
