The 100% minimum CTR at 1 mA forward current means the output transistor can saturate with as little as 1 mA LED drive, suiting low-power logic interfaces. The maximum CTR of 1200% warns of wide gain spread; the design must tolerate the full range without saturating the output stage. ## 80 V / 80 mA output – drives relays and logic gates directly Output transistor rated for 80 V maximum and 80 mA continuous current — enough to switch a relay coil or a logic input without a buffer transistor. The 400 mV max Vce saturation at rated current keeps conduction loss low, important for thermal budget in dense PCB layouts. ## 3 µs rise/fall – fits 100 kHz switching applications Typical rise and fall times of 3 µs each support switching frequencies up to roughly 100 kHz, adequate for isolated gate drive of low-power MOSFETs or for digital isolator replacement in non-critical paths. The 1.3 V max forward voltage and 50 mA max forward current define the LED drive budget — a series resistor from a rail can set the 1 mA operating point. ## Industrial temperature grade – -40°C to 110°C Operating temperature range of -40°C to 110°C qualifies the part for outdoor telecom cabinets, factory-floor PLC modules, and under-hood automotive auxiliary circuits. The 4-SMD gull-wing package is compatible with standard reflow soldering profiles; no special handling beyond MSL level typical for this package type.","metaTitle":"FODM124R2V onsemi Optoisolator – 3750Vrms, Transistor Output","metaDescription":"onsemi FODM124R2V optoisolator: 3750Vrms isolation, 100%–1200% CTR at 1 mA, transistor output, 4-SMD gull-wing.
