That figure is the one-minute withstand voltage per UL1577 — for a 250 VAC or 60 VDC working voltage, the margin is comfortable; for 400 VDC bus isolation you need a higher-rated part. The 8-SOIC footprint saves board space compared to DIP-8, but the creepage distance is shorter, so keep the isolation barrier clear of copper on adjacent layers. ## CTR range and drive current sizing Current transfer ratio is specified at 100% minimum, 200% maximum, both at If=10 mA. A CTR of 100% means 10 mA LED current can sink 10 mA at the output — enough to drive a logic gate input or a low-power relay coil. The 150 mA absolute maximum output current is a ceiling, not a continuous rating; the practical limit is set by the CTR and the 30 V output breakdown. If the load needs more than 10 mA, increase the LED drive proportionally, but stay under the 60 mA absolute maximum forward current. Rise time is 3.2 µs typical, fall time 4.7 µs typical. Turn-on time is 7.5 µs, turn-off 5.7 µs. For a 10 kHz PWM signal (100 µs period), the rise and fall edges consume about 8% of the period — acceptable for many industrial I/O interfaces. For 100 kHz serial data, the timing asymmetry will distort the duty cycle; consider a logic-output optocoupler instead. onsemi lists the MOC207M as Active and ROHS3 compliant.","metaTitle":"MOC207M Optoisolator, 2500Vrms, Transistor Output, onsemi","metaDescription":"onsemi MOC207M single-channel optoisolator, 2500Vrms isolation, DC input, transistor with base output, 8-SOIC, -40°C to 100°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Box","Input Type":"DC","Output Type":"Transistor with Base","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"2500Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-40°C ~ 100°C","Rise / Fall Time (Typ)":"3.2µs, 4.7µs","Voltage - Output (Max)":"30V","Supplier Device Package":"8-SOIC","Current - Output / Channel":"150mA","Current Transfer Ratio (Max)":"200% @ 10mA","Current Transfer Ratio (Min)":"100% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.15V","Turn On / Turn Off Time (Typ)":"7.5µs, 5.7µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.87","priceTiers":[{"qty":1,"price":"$1.04000","currency":"USD"},{"qty":10,"price":"$0.68100","currency":"USD"},{"qty":100,"price":"$0.44590","currency":"USD"},{"qty":1000,"price":"$0.35203","currency":"USD"},{"qty":2000,"price":"$0.32856","currency":"USD"},{"qty":5000,"price":"$0.31682","currency":"USD"},{"qty":10000,"price":"$0.31213","currency":"USD"},{"qty":25000,"price":"$0.30509","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/05fa790c98d78477070a515d3f0e0692.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MOC207M/alternatives.json"},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) of MOC207M?","answer":"The CTR is 100% minimum and 200% maximum, both measured at If=10 mA.
