Current transfer ratio (CTR) is specified at 63% min, 125% max, measured at If=10mA — this spread defines the input-drive margin the designer must budget across temperature and LED ageing. Switching is characterised by 1µs rise / 2µs fall time (typ) and 2µs turn-on / 3µs turn-off time (typ) — adequate for 50-60 Hz line synchronisation and low-speed logic isolation, but too slow for high-frequency PWM or serial data links. ## Output ratings and temperature range Output transistor withstands up to 70V Vce and 50mA continuous collector current — suitable for driving 24V PLC inputs, relay coils, or DC loads within the current limit. Vce(sat) is clamped at 300mV max at the rated collector current — the saturation voltage is low enough to keep power dissipation in the phototransistor under 15mW at 50mA, avoiding thermal runaway at high ambient. Full -55°C to 100°C operating temperature range covers industrial and outdoor enclosures — the LED forward voltage (1.35V typ at 10mA) shifts about -2mV/°C, so the input drive circuit must hold the LED current within the 100mA absolute maximum across temperature.","metaTitle":"CNY17F23SD onsemi Optoisolator, 5300Vrms, 63-125% CTR, 6-SMD","metaDescription":"onsemi CNY17F23SD optocoupler, 5300Vrms isolation, 63-125% CTR, 70V output, -55°C to 100°C.
