Its 5300Vrms isolation rating means the input and output sides are galvanically separated by a dielectric barrier certified for reinforced insulation in mains-connected circuits — sufficient for IEC 60950-1 basic isolation at 250V working voltage or reinforced isolation at lower voltages. The 63% to 125% current transfer ratio at 10 mA forward current defines the gain window for the phototransistor. At the minimum CTR of 63%, a 10 mA LED drive yields at least 6.3 mA collector current — enough to saturate the output transistor for a logic-level signal when the collector resistor is sized correctly. onsemi has marked the CNY17F2SD as Obsolete. Stock is lot-specific and date-code verified at the time of RFQ. No last-time-buy window remains open; any available inventory is already manufactured and held in distribution. The 6-SMD Gull Wing package (supplier device package 6-SMD) is a surface-mount footprint designed for reflow soldering. The Gull Wing leads provide visual solder-joint inspection access and moderate standoff height for cleaning under the body. Operating temperature range -55°C to 100°C covers industrial and military-grade environments. The 70V maximum output voltage and 50mA continuous output current suit it for driving logic inputs, relay coils through a driver transistor, or low-power DC loads in isolated feedback loops.","metaTitle":"onsemi CNY17F2SD Optoisolator, 5300Vrms, 63-125% CTR","metaDescription":"onsemi CNY17F2SD single-channel transistor output optocoupler. 5300Vrms isolation, 63-125% CTR at 10mA, -55°C to 100°C.
