Overview
The CNY17F-4X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base terminal for improved switching performance. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a maximum collector current of 50mA, and a forward current of 60mA. The typical forward voltage is 1.65V, with a saturation voltage of 400mV. The current transfer ratio ranges from 160% to 320%. Switching times are specified as 2µs rise and 2µs fall time.
Feature Summary
- Provides high-voltage isolation between input and output circuits using optical coupling technology.
- Integrates an NPN phototransistor with a dedicated base terminal to enhance switching speed and linearity.
- Designed for surface-mount installation in compact electronic assemblies requiring reliable signal transmission.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessors and logic families
- Power supply feedback loops
Procurement Notes
Verify the specific suffix X009 corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 160-320% current transfer ratio meets the design requirements for the intended load conditions. Ensure compatibility with standard surface-mount reflow soldering profiles during assembly planning.
Selection Notes
Select this component when a surface-mount footprint is required alongside high-speed switching capabilities provided by the base-connected phototransistor. Compare the 160-320% CTR against other variants like the CNY17F-3 or CNY17F-2 if different gain characteristics are needed. Verify that the 5000 Vrms insulation rating satisfies the safety standards applicable to the target application environment.
Part Context
This part belongs to the CNY17 series of transistor output optocouplers. The 'F' designation indicates a lead-free variant compliant with RoHS directives. The 'X009' suffix typically denotes specific packaging options such as tape and reel, distinguishing it from tube-packaged DIP versions like the CNY17F-4.
Replacement Considerations
Direct substitutes include CNY17F-4X016 for similar specifications in alternative packaging. Other family members like CNY17-2X009T offer comparable electrical characteristics but may differ in package type or manufacturing origin.
