Device identity and key isolation parametrics
The onsemi CNY1723SD is a single-channel optoisolator with a DC input LED and a phototransistor output that includes a base connection for external bias or speed-up networks. Rated for 5300Vrms isolation, this part suits applications requiring reinforced galvanic separation between control and load circuits, such as industrial PLC I/O modules or medical patient-monitoring interfaces.
Supplied in a 6-SMD Gull Wing package (supplier device package 6-SMD), the CNY1723SD is a surface-mount part intended for reflow soldering on standard PCB land patterns. The Tape & Reel (TR) packaging format supports automated pick-and-place assembly for volume production.
