Current transfer ratio spans 160% min to 320% max at If=10 mA, Vce=5 V. The wide CTR band means the output transistor saturates reliably across the full production spread — no need to bin or hand-select parts for logic-level interface designs. Switching speed is moderate: 1 µs rise, 2 µs fall typical, with turn-on/turn-off times of 2 µs and 3 µs respectively. This suits 10-100 kHz isolated gate drive or status-feedback loops, but not high-frequency SMPS feedback where a faster optocoupler or digital isolator is preferred. Supplied in a 6-DIP (0.400\", 10.16 mm) through-hole package — the standard 0.100-inch pin pitch and 0.300-inch row spacing match legacy DIP sockets or wave-solder footprints. The 6-DIP supplier device package is the same body as the industry-standard 6-pin DIP optocoupler, so the land pattern is interchangeable with parts like the 4N35 or PC817 families. Operating temperature range of -55°C to 100°C covers industrial and extended-commercial environments — the lower limit suits outdoor telecom cabinets and cold-chain equipment.","metaTitle":"onsemi CNY174W Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY174W optocoupler, 1-channel DC input, transistor output, 5300Vrms isolation, 160-320% CTR at 10mA.
