This is a single-channel optocoupler in a 6-DIP through-hole package, rated for 5300Vrms isolation — a standard spec for industrial isolation barriers in power supplies, motor drives, and PLC digital inputs. ## Key ratings and what they mean for the BOM Current transfer ratio (CTR) is guaranteed between 40% and 80% at 10 mA forward current — this band is typical for general-purpose optocouplers and ensures the output transistor saturates reliably when driving a logic input or a low-current relay coil. The output transistor handles up to 70 V collector-emitter and 50 mA continuous current, with a 300 mV saturation voltage at rated drive — sufficient for 5 V or 24 V logic-level interfaces in industrial control. Switching speed is modest: 1 µs rise, 2 µs fall typical, with turn-on/turn-off times of 2 µs and 3 µs respectively. This limits the part to signals below about 100 kHz — fine for 50/60 Hz line sync or slow PLC inputs, not for high-speed data isolation. Operating temperature spans -55°C to 100°C, covering industrial and some military/aerospace environments. The 5300Vrms isolation rating meets reinforced insulation requirements per IEC 60950-1 for mains-connected equipment. The 6-DIP footprint is shared across many optocouplers, so a board layout designed for a similar part may accept this one without a spin.","metaTitle":"onsemi CNY171300 Optoisolator, 5300Vrms, 6-DIP","metaDescription":"onsemi CNY171300 optocoupler, 1-channel DC input, transistor output, 5300Vrms isolation, -55°C to 100°C.
