That isolation voltage qualifies it for reinforced insulation in mains-connected circuits — think isolated feedback loops in switch-mode supplies, IGBT gate-drive interfaces, or any signal crossing a safety barrier where the working voltage stays under the 5300Vrms test ceiling. The current-transfer ratio is specified at 19% minimum with a 16mA forward current. That 19% floor is the number to design to after you budget CTR aging — the LED in any optocoupler fades over time, and a design that starts at 19% has less headroom than one starting at 50%. For a 5V logic input needing 2mA at the output, the input drive must supply at least 10.5mA through the LED to guarantee the output turns on at end of life. ## Switching speed and output drive — what 200ns buys you Typical turn-on and turn-off times are both 200ns, placing this part in the medium-speed optocoupler class. It is fast enough for 1MHz-ish data rates or PWM signals up to a few hundred kilohertz, but not a logic-level digital isolator for high-speed serial buses. The output is a phototransistor with the base brought out — that base pin lets you add a resistor to tailor the switching threshold or speed up the turn-off with a base-emitter shunt, a flexibility you lose in a Darlington or logic-output optocoupler. Maximum output current per channel is 8mA, and the output voltage tops out at 15V. That output stage drives CMOS or TTL logic inputs directly, but not a relay coil or an LED indicator without a buffer transistor. ## Package, temperature range, and compliance Housed in an 8-SMD Gull Wing package, the 6N136-X019T uses the standard SOP-8 land pattern common across the 6N136 family. The surface-mount gull-wing leads are inspectable after reflow and tolerate the thermal cycling of industrial environments. Operating temperature spans -55°C to 100°C, covering industrial and military-grade applications — motor drives, base-station power supplies, and outdoor instrumentation all fit within that window.","metaTitle":"Vishay 6N136-X019T Optocoupler, 5300Vrms, 8-SMD, Active","metaDescription":"Vishay 6N136-X019T single-channel optocoupler, 5300Vrms isolation, 19% min CTR at 16mA, 200ns switching, -55°C to 100°C, 8-SMD Gull Wing, ROHS3, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor with Base","Mounting Type":"Surface Mount","Package / Case":"8-SMD, Gull Wing","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5300Vrms","Operating Temperature":"-55°C ~ 100°C","Voltage - Output (Max)":"15V","Supplier Device Package":"8-SMD","Current - Output / Channel":"8mA","Current Transfer Ratio (Min)":"19% @ 16mA","Voltage - Forward (Vf) (Typ)":"1.33V","Turn On / Turn Off Time (Typ)":"200ns, 200ns","Current - DC Forward (If) (Max)":"25 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.79","priceTiers":[{"qty":1,"price":"$1.79000","currency":"USD"},{"qty":10,"price":"$1.13300","currency":"USD"},{"qty":100,"price":"$0.83840","currency":"USD"},{"qty":500,"price":"$0.77044","currency":"USD"},{"qty":1000,"price":"$0.63448","currency":"USD"},{"qty":2000,"price":"$0.60276","currency":"USD"},{"qty":5000,"price":"$0.58916","currency":"USD"},{"qty":10000,"price":"$0.57556","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/664f420bdb271b9e25c8a9f9b0bd25fb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/6N136-X019T/alternatives.json"},"ai":{"faq":[{"question":"What is the minimum CTR of the 6N136-X019T and why does it matter?","answer":"The minimum current-transfer ratio is 19% at a forward current of 16mA. This is the worst-case gain after the LED ages — design your input drive so the output can still sink the required load current at 19% CTR, not at the typical value. A design that starts at 19% has less aging headroom than one starting at 50%, so factor in a 20-30% CTR degradation over 10 years."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/6N136-X019T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/6N136-X019T when reusing this data.
