It covers reinforced insulation requirements in mains-referenced circuits per IEC 60950-1 and IEC 62368-1, suitable for isolating low-voltage control from line-voltage power stages. Current transfer ratio (CTR) is specified at 100% minimum and 200% maximum, both at If=10mA. This bin (F3) guarantees a minimum CTR of 100%, meaning the output transistor conducts at least as much collector current as the LED forward current — a tighter band than the standard CNY17 family. The 200% ceiling prevents overdrive in the output stage. The 70V output voltage rating and 50mA continuous output current define the load-side capability — suitable for driving logic inputs, PLC I/O modules, or low-power relays up to that voltage and current. Typical turn-on time is 2µs and turn-off time 3µs, with rise/fall times of 4µs and 3.5µs max. These switching speeds support data rates up to roughly 100 kbit/s — adequate for status feedback, isolated serial communication, and slow-switching power supply feedback loops. Housed in a 6-DIP through-hole package with 0.400-inch (10.16 mm) body width. The 2.54 mm pin pitch matches standard DIP footprints and breadboard layouts. The through-hole assembly requires wave soldering or hand-solder — no reflow profile needed, which simplifies prototyping and low-volume production.","metaTitle":"onsemi CNY17F3TM Optoisolator, 4170Vrms, 6-DIP","metaDescription":"onsemi CNY17F3TM optocoupler, 1-channel DC input transistor output, 4170Vrms isolation, 100-200% CTR at 10mA, 6-DIP through-hole.
