Overview
The Fairchild Semiconductor CNY17F4 is a single-channel transistor output optocoupler featuring an NPN phototransistor. It provides a minimum collector-emitter breakdown voltage of 70 V and supports a maximum forward current of 60 mA with a forward voltage of 1.65 V. The device offers a nominal current transfer ratio of 160% and a maximum insulation voltage of 5300 V. Operating within a temperature range of -55 °C to 100 °C, it dissipates up to 0.15 W and exhibits a maximum response time of 10 µs.
Feature Summary
- Integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor for signal isolation.
- Provides high insulation voltage capability suitable for power supply applications.
Applications
- Power supply feedback circuits
- Signal isolation in industrial control systems
Procurement Notes
Verify the specific manufacturer source, as Fairchild Semiconductor assets were acquired by onsemi. Confirm that the component matches the original Fairchild specifications rather than subsequent manufacturing changes. Check RoHS compliance status and ensure the package type aligns with design requirements before procurement.
Selection Notes
Select this component when a standard single-channel isolation solution with moderate speed is required. Ensure the circuit design accommodates the 160% typical current transfer ratio. Verify that the 70 V collector-emitter voltage rating meets the load requirements and that the operating temperature range fits the environmental conditions.
Part Context
This device belongs to the CNY17 family of optocouplers, which are widely used for general-purpose isolation. The CNY17F4 variant specifically denotes the 160% CTR binning. These components are commonly found in legacy designs for AC/DC converters and digital signal transmission where galvanic isolation is necessary.
Replacement Considerations
Check for equivalents from Vishay (CNY17F-4) or Everlight. Note that onsemi may produce updated versions; verify pinout compatibility and electrical parameters against the original datasheet before substitution.
