Each channel can handle up to 70 V at 50 mA on the output side, with a current transfer ratio guaranteed between 100% and 600% at a forward current of 5 mA. The input accepts both AC and DC signals, and the transistor output gives you a clean, isolated logic-level or low-side switch signal. ## CTR range — what 100% to 600% at 5 mA means for your design The 100% minimum CTR at 5 mA is the number to design around: it guarantees that with 5 mA in the LED, the phototransistor can sink at least 5 mA on the output. That gives you comfortable margin to drive a logic gate input or a low-power relay coil without extra gain stages. The 600% max tells you the part can be quite sensitive — if your load is light, you may need a pull-up resistor that doesn't let the output saturate too hard, slowing the turn-off. The 3 µs turn-on and 2.3 µs turn-off times (typical) are fine for 10 kHz-ish switching or status feedback; they're not meant for high-speed data links. ## Package and mounting — surface-mount gull wing, tube delivery The tube is the shipping medium — the parts come in a rigid anti-static tube, not tape-and-reel, so plan your pick-and-place feeder setup accordingly if you're running high volume. For a field repair or a small batch, tube delivery is actually easier to handle: you can grab one part at a time without unspooling a reel.","metaTitle":"ILQ620GB-X009 Vishay Optocoupler, 4-Ch, 5300 Vrms, 16-SMD","metaDescription":"Vishay ILQ620GB-X009 quad-channel optocoupler with 5300 Vrms isolation, 100%-600% CTR at 5 mA, transistor output, -55°C to 100°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Input Type":"AC, 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","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"20µs, 2µs","Voltage - Output (Max)":"70V","Supplier Device Package":"16-SMD","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"600% @ 5mA","Current Transfer Ratio (Min)":"100% @ 5mA","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":"$4.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.19000","currency":"USD"},{"qty":10,"price":"$2.96500","currency":"USD"},{"qty":100,"price":"$2.42860","currency":"USD"},{"qty":500,"price":"$2.04738","currency":"USD"},{"qty":1000,"price":"$1.87793","currency":"USD"},{"qty":2000,"price":"$1.80028","currency":"USD"},{"qty":5000,"price":"$1.76498","currency":"USD"}]},"links":{"datasheetUrl":"https://www.vishay.com/docs/83653/ild620.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) range for ILQ620GB-X009?","answer":"The CTR is guaranteed between 100% minimum and 600% maximum, both measured at a forward current of 5 mA."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/ILQ620GB-X009","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/ILQ620GB-X009 when reusing this data.
