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.","metaTitle":"onsemi CNY1723SD Optoisolator, 5300Vrms, Obsolete","metaDescription":"onsemi CNY1723SD optoisolator, 1-channel DC input, transistor output, 5300Vrms isolation, 63-125% CTR at 10mA.
