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. ## Switching speed and timing budget 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. ## Lifecycle and procurement posture 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","stockQuantity":0,"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},"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.
