Overview
The CNY17F1SR2M is a transistor output optocoupler manufactured by Fairchild Semiconductor. It features a single channel with a phototransistor output and DC input type. The device provides high isolation voltage of 7500 Vrms and supports a collector-emitter breakdown voltage of 70V minimum. It operates within a temperature range of -55°C to 100°C. The component is housed in a surface mount package, specifically an MDIP configuration, and is RoHS compliant.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Surface mount packaging design suitable for automated assembly processes
- Wide operating temperature range ensuring reliability in diverse environmental conditions
Applications
- Power supply regulators
- Microprocessor inputs
- Industrial controls
- Digital logic inputs
Procurement Notes
Verify the specific suffix 'SR2M' confirms the surface mount tape-and-reel packaging format. Confirm the manufacturer origin as Fairchild or onsemi, noting corporate acquisitions may affect branding. Ensure the part meets current RoHS3 compliance standards required for modern electronics manufacturing. Check for any lead-free plating specifications if soldering compatibility is critical.
Selection Notes
Select this component when surface mount technology is required for the CNY17 series functionality. The 7500 Vrms isolation rating makes it suitable for high-voltage noise immunity applications. Consider the 70V collector-emitter breakdown voltage for load switching requirements. Verify that the MDIP package dimensions fit the target PCB layout constraints compared to through-hole alternatives.
Part Context
This part belongs to the CNY17 series, which couples a Gallium Arsenide IRED with an NPN phototransistor. The series includes various packages and isolation ratings. The 'F1' designation typically indicates specific Current Transfer Ratio groups. The 'SR2M' suffix denotes the surface mount reel packaging variant, distinguishing it from standard DIP versions.
Replacement Considerations
Direct substitutes include other CNY17-1 variants in surface mount packages such as CNY17-1SR2V-M. Verify pinout compatibility and isolation voltage ratings before substitution. Cross-reference with ON Semiconductor equivalents if Fairchild stock is unavailable.
