In a PLC digital input module or a motor-drive feedback interface, this barrier protects the low-voltage logic side from transient surges on the field side. The 6-DIP through-hole package (0.300\" lead spacing) mates with standard 0.100\" pitch DIP sockets or solders directly into a plated through-hole board — no reflow profile needed, and the creepage distance between pins on the 7.62mm-wide body supports the 5300Vrms rating in clean-air environments. ## CTR, Vce(sat), and output drive — the real selection numbers This means with 10 mA forward current the output transistor saturates to a Vce of 300mV max — the CTR floor guarantees the output can sink the rated 50 mA without dropping out of saturation. For a 24V PLC input, the 70V Vce(max) rating leaves headroom above the rail. Switching speed is modest: 1 µs rise, 2 µs fall, with turn-on/turn-off times of 2 µs and 3 µs typical. This suits 10–100 kHz data rates in isolated serial interfaces or slow digital I/O, but not high-speed fieldbus couplers.","metaTitle":"onsemi CNY173300 Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY173300 optoisolator, 5300Vrms isolation, 100-200% CTR, 70V output, -55 to 100°C.
