Overview
The CNY17F43S is a single-channel surface-mount phototransistor optocoupler from onsemi. It features an NPN phototransistor output with no base connection, housed in a compact SMD-DIP-6 package. The device provides high isolation voltage of 7500 Vrms and supports a maximum forward current of 100 mA. Key electrical parameters include a collector-emitter saturation voltage of 400 mV max, a collector current of 50 mA max, and a power dissipation of 250 mW. Operating temperature ranges from -55°C to +100°C.
Feature Summary
- Surface-mount design for automated assembly
- High isolation voltage capability
- NPN phototransistor output without base terminal
Applications
- General-purpose signal isolation
- Industrial control systems
- Consumer electronics interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to procurement. Note that availability may be restricted; check current stock levels and lead times with suppliers. Ensure packaging integrity matches specified bulk quantities.
Selection Notes
Select this component for applications requiring surface-mount isolation with standard phototransistor outputs. Consider the 7500 Vrms isolation rating for safety-critical circuits. Evaluate thermal management needs given the 250 mW power dissipation limit. Verify compatibility with existing PCB footprint designs for the SMD-DIP-6 package.
Part Context
Part of the CNY series, widely used for general-purpose isolation. The CNY17F43S variant specifically offers surface-mount convenience compared to through-hole equivalents like the CNY17F4M. It maintains similar electrical characteristics to other CNY17 variants while adapting to modern SMT manufacturing processes.
Replacement Considerations
Direct pin-compatible replacements within the CNY17 family should be verified against specific suffix requirements. Cross-reference datasheets for identical isolation ratings and output configurations before substitution.
