No official successor or second-source order code is recorded. Sourcing is through independent distribution channels; quantities are lot-specific and confirmed at RFQ. ## 5300Vrms isolation — what it means for the BOM Rated for 5300Vrms isolation, this optoisolator provides reinforced insulation suitable for safety-critical galvanic separation between a DC control input and a transistor output. The 1µs rise and 2µs fall times (typical) support switching up to low-kHz signal rates in industrial I/O, PLC, or motor-drive feedback paths. Current transfer ratio (CTR) is specified at 160% minimum and 320% maximum, both at 10mA forward current. This bin ensures consistent gain across the operating temperature range of -55°C to 100°C, which covers industrial and some military-grade environments. Output transistor is rated for 70V maximum collector-emitter voltage and 50mA continuous current, with a saturation voltage of 300mV max. The 100mA maximum DC forward current on the input side sets the LED drive limit. Supplied in a 6-SMD Gull Wing package (6-SMD supplier device package), surface-mount compatible with standard reflow profiles. The Tape & Reel (TR) format suits automated pick-and-place assembly. The 6-pin footprint matches the industry-standard DIP-6 SMD layout used across the CNY17 family.","metaTitle":"onsemi CNY17F43SD Optoisolator, 5300Vrms, 6-SMD Gull Wing","metaDescription":"onsemi CNY17F43SD optoisolator, 5300Vrms isolation, 160-320% CTR at 10mA, DC input, transistor output, -55 to 100°C.
