It provides 5300Vrms galvanic isolation between the DC input LED and the phototransistor output — sufficient for reinforced insulation in mains-referenced circuits such as motor-drive feedback, PLC digital inputs, and isolated serial interfaces. The 6-DIP footprint is a legacy through-hole format that mates with standard 0.100-inch pitch sockets or wave-solder holes. The 7.62mm (300-mil) body width is the common DIP-6 outline, so replacement or second-source parts in the same package drop into the same board layout without a spin. ## 40-80% CTR band and switching speed This 2:1 CTR spread is typical for a standard transistor-output coupler — the designer sizes the pull-up resistor and the downstream logic threshold to guarantee a logic-high at the minimum CTR and avoid saturation at the maximum. Turn-on and turn-off times are 2µs and 3µs typical respectively, with rise and fall times of 1µs and 2µs. This places the CNY17F1300 in the medium-speed band — adequate for 10-100 kbps data rates or 50/60 Hz mains zero-cross detection, but not for high-speed fieldbus isolation. The output transistor is rated for 70V VCEO max and 50mA continuous collector current. The 300mV VCE(sat) at the rated current means the output drops less than a logic-low threshold when the phototransistor is fully on, so it drives TTL or 5V CMOS inputs directly without a buffer. onsemi has marked the CNY17F1300 as Obsolete. The part is no longer available through the standard authorized distribution channel. Availability is lot-specific and confirmed at RFQ — no standing inventory is held. The 6-DIP footprint and 40-80% CTR band mean that a functional replacement from another manufacturer (e.g., Vishay, Toshiba, or Broadcom) with the same package and similar CTR range is a viable BOM hedge, but pin-compatibility must be verified against the specific replacement datasheet. ## Temperature grade and environment Rated for -55°C to +100°C operating ambient — the full industrial temperature range with margin into military-grade cold. The 1.35V typical forward voltage at 10mA IF and 100mA absolute-maximum forward current are standard for an infrared LED coupler. The 5300Vrms isolation rating is tested per the optoisolator standard (likely IEC 60747-5-5 or equivalent). This level supports reinforced insulation for 300VAC working voltage systems with a 1.2/50µs surge withstand requirement — typical for motor-drive I/O, industrial power supplies, and medical equipment where patient-contact isolation is not required.","metaTitle":"onsemi CNY17F1300 Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY17F1300 single-channel transistor output optoisolator, 5300Vrms isolation, 40-80% CTR at 10mA, 6-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"CNY17","Voltage - Isolation":"5300Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C~100°C","Rise / Fall Time (Typ)":"1µs, 2µs","Voltage - Output (Max)":"70V","Supplier Device Package":"6-DIP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"80% @ 10mA","Current Transfer Ratio (Min)":"40% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.35V","Turn On / Turn Off Time (Typ)":"2µs, 3µs","Current - DC Forward (If) (Max)":"100 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4a47ea3b51cbb13a83c8d83e21910005.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F1300/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the CNY17F1300?","answer":"onsemi does not list an official successor.
