It comes in a 4-SMD Gull Wing package for surface-mount assembly. The current transfer ratio (CTR) is specified at 100% minimum and 200% maximum when the LED forward current is 10 mA, giving a predictable gain window for logic-level or low-power signal isolation. ## Active lifecycle and ROHS3 compliance — no end-of-life worry It is also ROHS3 compliant, meeting the latest restriction-of-hazardous-substances directive. The 5300 Vrms isolation rating suits applications requiring reinforced insulation — think industrial motor drives, power supplies, or medical equipment where a fault on the primary side must not reach the secondary. The transistor output can sink up to 50 mA and block up to 70 V, enough to drive a microcontroller GPIO or a small relay directly.","metaTitle":"SFH617A-3X017T Optoisolator, 5300Vrms, 4-SMD Gull Wing","metaDescription":"SFH617A-3X017T Vishay optocoupler: 5300Vrms isolation, 100-200% CTR at 10mA, transistor output, -55 to 110°C.
