This places the CNY17F1W in the standard-speed phototransistor optocoupler class — adequate for 50/60 Hz line synchronisation, relay driver isolation, and digital signal feedback at low-to-moderate data rates. ## CTR range and drive margin Current transfer ratio is guaranteed between 40% and 80% at a forward current of 10 mA. This bin (the '1' suffix) gives a narrower CTR window than the wide-bin CNY17 — useful when the downstream logic or microcontroller input needs a predictable collector current without overdriving the LED. At 10 mA forward, the minimum 40% CTR yields 4 mA at the output transistor collector — enough to saturate a TTL or 5 V CMOS input with a 1 kΩ pull-up resistor. The maximum output current per channel is 50 mA, and the output transistor can block up to 70 V. Housed in a 6-pin DIP with 0.400-inch (10.16 mm) body width, through-hole mounting. The supplier device package is listed as 6-DIP. This is the standard dual-in-line phototransistor optocoupler footprint — compatible with legacy layouts and hand-assembly or wave-solder processes. The tube packaging is typical for through-hole DIP parts handled in low-to-medium volume assembly.","metaTitle":"onsemi CNY17F1W Optoisolator, 5300Vrms, Through Hole DIP","metaDescription":"onsemi CNY17F1W optocoupler, 5300Vrms isolation, 40-80% CTR at 10mA.
