That isolation rating covers reinforced insulation requirements per IEC 60950-1 for mains-referenced circuits — think PLC digital inputs, motor-drive feedback, or any 24V fieldbus interface where ground loops and transients need a clean break. ## CTR band and drive margin That 2:1 spread means the downstream logic sees a consistent collector current across the production band — no need to overdrive the LED or oversize the pull-up resistor for worst-case CTR. Switching speed is defined by 4µs rise and 3.5µs fall times (max), with turn-on and turn-off times of 2µs and 3µs typical. That puts the usable data rate around 100 kbps — fine for 24V DC discrete signals, slow serial buses like RS-232, or status feedback from a relay output. For faster isolation channels like CAN or SPI, a digital isolator or high-speed optocoupler would be the right call. ## Output ratings and temperature range The output transistor is rated for 70V Vce(max) and 50mA continuous collector current. That 70V ceiling covers 48V industrial rails and 24V systems with margin for transients. The 400mV Vce(sat) at rated current keeps dissipation low in the output stage — important when the part is packed into a dense SMD layout with limited copper to sink heat. Operating temperature spans -40°C to 100°C, which covers most industrial enclosures and outdoor cabinet installations. The 1.35V typical forward voltage at 10mA is standard for an IR LED — the drive circuit needs about 2V headroom above Vf to regulate the forward current through a series resistor. ## Package, mounting, and sourcing The surface-mount gull-wing leads are inspectable after reflow and tolerate thermal cycling better than a flat-lead package — a plus for boards that see temperature swings in the cabinet.","metaTitle":"onsemi CNY17F2SVM Optoisolator, 4170Vrms, 6-SMD","metaDescription":"onsemi CNY17F2SVM transistor output optocoupler, 4170Vrms isolation, 63-125% CTR at 10mA, 6-SMD gull wing.
