It is used wherever a control signal needs to cross a safety barrier — think PLC digital inputs, motor-drive feedback, AC mains zero-cross detect, or isolated serial links in industrial gear. The current transfer ratio is 100% minimum and 200% maximum at 10 mA forward current. The output transistor is rated for 70 V and 50 mA continuous, with a saturation voltage of 300 mV max. Rated from -55°C to 110°C operating, this part handles the full industrial temperature band and can sit in an engine-bay ECU or a rooftop solar inverter without derating. The storage range is wider, but the 110°C ceiling is the running limit — keep the junction below that if you are pushing the output current near the 50 mA max. ## Package and field-swap reality It comes in a 4-SMD gull-wing package (the 4-SMD supplier device package). That is the standard optocoupler footprint — four pins, two on each side. On site, with a basic iron and some solder wick, you can swap this in a parking lot. No hot-air station, no stencil. The gull-wing leads are visible, so you can inspect the joints after rework. ## Switching speed — what the timing numbers mean Rise time is 3 µs typical, fall time 4.7 µs typical; turn-on and turn-off are 6 µs and 5 µs respectively.","metaTitle":"VO615A-3X019T Optocoupler, 5000Vrms, 100-200% CTR, 4-SMD","metaDescription":"Vishay VO615A-3X019T optocoupler with transistor output, 5000Vrms isolation, 100-200% CTR at 10mA, -55 to 110°C.
