Its 5300Vrms isolation rating is the headline number — that is enough galvanic isolation for industrial motor drives, medical patient-interface barriers, and power-supply feedback loops where you need to keep the high-voltage side separate from the control logic. Each channel can switch up to 70V at 50mA, which covers most PLC input modules, relay drivers, and logic-level translation tasks. ## CTR window and switching speed Current transfer ratio is specified between 40% and 80% at a forward current of 10mA. That is a tight enough window to design a reliable logic interface without over-driving the LED or worrying about saturation at the output. Typical turn-on time is 3µs, turn-off 2.3µs — not a high-speed digital isolator, but fast enough for 100 kbps serial links, status feedback, and PWM gate drive at a few kHz. Rise and fall times are both 2µs typical, so the output edges are symmetrical. ## Temperature range and field-service reality Rated from -55°C to 100°C, this part handles the full military temperature range on the cold side and industrial hot-side environments. That means it is a candidate for outdoor telecom cabinets, engine-bay electronics, and any retrofit where the original part ran hot. The 16-SMD gull-wing package is rework-friendly with a standard hot-air station — no BGA, no hidden pads. On a customer site with just a soldering iron and a flux pen, you can swap this part if the board has through-hole or SMD pads accessible. ## Lifecycle and compliance Listed as Active in the lifecycle stage, so this is still a standard production part — no last-time-buy pressure, no need to stockpile for legacy BOMs. It is ROHS3 compliant, which clears it for current RoHS-regulated markets without an exemption. The DC input type means it works with standard logic-level signals; no AC line coupling concerns.","metaTitle":"ILQ615-1X009 Optocoupler, 5300Vrms Isolation","metaDescription":"ILQ615-1X009 quad optocoupler with 5300Vrms isolation, 4 transistor outputs, 40-80% CTR at 10mA, -55 to 100°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"16-SMD, Gull Wing","lifecycle_stage":"eol_hot","Number of Channels":"4","Voltage - Isolation":"5300Vrms","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"2µs, 2µs","Voltage - Output (Max)":"70V","Supplier Device Package":"16-SMD","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"80% @ 10mA","Current Transfer Ratio (Min)":"40% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.15V","Turn On / Turn Off Time (Typ)":"3µs, 2.3µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.12","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.12000","currency":"USD"},{"qty":10,"price":"$2.20800","currency":"USD"},{"qty":100,"price":"$1.80840","currency":"USD"},{"qty":500,"price":"$1.52454","currency":"USD"},{"qty":1000,"price":"$1.39838","currency":"USD"},{"qty":2000,"price":"$1.34055","currency":"USD"},{"qty":5000,"price":"$1.31426","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8ca47a6a3221ec2eaeeb28b390a0355b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ILQ615-1X009 be used in high-temperature applications?","answer":"The 100°C upper limit is sufficient for outdoor enclosures, engine compartments, and factory-floor equipment, but not for extended exposure above 100°C — that would require a higher-temperature rated part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/ILQ615-1X009","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/ILQ615-1X009 when reusing this data.
