For a BOM that needs a drop-in replacement, the base product number CNY17 family includes active variants with similar pinout and isolation ratings, but no direct pin-compatible substitute is documented. A board-level review of the CTR bin and package is required before substituting. ## 5300Vrms isolation, 100-200% CTR at 10mA Rated for 5300Vrms isolation between input and output — this covers reinforced insulation requirements in mains-referenced circuits like motor drive feedback, SMPS secondary sensing, and PLC digital input modules. Current transfer ratio is binned 100% to 200% at 10mA forward current. The 100% minimum guarantees the output transistor saturates with a 10mA LED drive, leaving margin for LED aging over the -55°C to 100°C operating range. ## 6-SMD Gull Wing — surface-mount assembly Supplied in a 6-SMD Gull Wing package (6-SMD supplier device package), on Tape & Reel. Maximum forward current is 100mA, so a 330-ohm resistor at 5V keeps the drive within the 10mA test condition for the CTR bin.","metaTitle":"onsemi CNY17F33SD Optoisolator, 5300Vrms, Obsolete","metaDescription":"onsemi CNY17F33SD optoisolator, 1-channel DC input, transistor output, 5300Vrms isolation, 100-200% CTR at 10mA.
