CNY17F4SVM

Overview

The CNY17F4SVM is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor. It integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor in a surface-mount 6-pin package. The device provides galvanic isolation of 4170Vrms between input and output circuits. Key electrical specifications include a minimum collector-emitter breakdown voltage (BVCEO) of 70V, a maximum forward current of 100mA, and a maximum dark current of 50nA. The unit operates within a temperature range of -55°C to 100°C and features a nominal current transfer ratio of 160%.

Feature Summary

• Integrates a Gallium Arsenide IRED coupled with an NPN phototransistor for efficient signal transmission
• Provides high-voltage galvanic isolation suitable for noise-sensitive environments
• Features a minimum collector-emitter breakdown voltage of 70V for robust output protection
• Compliant with UL and VDE safety standards for industrial applications

Applications

• Power supply regulators
• Microprocessor inputs
• Industrial controls
• Digital logic inputs

Procurement Notes

Verify the specific suffix 'SVM' corresponds to the required surface-mount package type and lead-free compliance status. Confirm that the 4170Vrms isolation rating meets the system's safety requirements. Ensure the 70V minimum BVCEO is sufficient for the intended load conditions. Check for RoHS and REACH compliance documentation prior to final procurement decisions.

Selection Notes

Select this component when a surface-mount transistor output optocoupler is required for high-isolation applications. The 160% nominal current transfer ratio supports standard logic interfacing. Consider the 6-SMD package constraints for PCB layout. Verify thermal management capabilities given the 100°C maximum operating temperature limit.

Part Context

This part belongs to the CNY17 series of optoisolators from Fairchild Semiconductor. The series includes various configurations such as DIP packages and different isolation ratings. The 'F4' designation typically indicates a specific binning or performance group within the product line, while 'SVM' denotes the surface-mount packaging variant.

Replacement Considerations

Direct replacements may include other CNY17 series variants with compatible pinouts and isolation ratings. Verify that substitute parts maintain the same 70V BVCEO and 4170Vrms isolation specifications. Ensure the replacement matches the surface-mount footprint and lead-free material composition.
