Overview
The CNY17F4300W is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor. It features a Gallium Arsenide infrared emitting diode coupled with an NPN phototransistor, providing electrical isolation in a 6-pin DIP package. Key electrical parameters include a maximum isolation voltage of 5300 Vrms and a collector-emitter breakdown voltage of 70 V minimum. The device supports a maximum forward current of 100 mA and a collector current of 50 mA. It operates within a temperature range of -55°C to 100°C and offers a typical response time of 1 µs for rise and 2 µs for fall.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using a GaAs IRED and NPN phototransistor configuration.
- Designed for through-hole mounting in compact 6-DIP packages suitable for power supply applications.
- Offers UL recognition and VDE approval for compliance with international safety standards.
Applications
- Power supply feedback loops
- Signal isolation in industrial control systems
- Microcontroller interface circuits
Procurement Notes
Verify component authenticity due to obsolete status. Confirm RoHS compliance and packaging type (tube) with the supplier. Check for alternative sources as original production has ceased. Ensure storage conditions meet semiconductor handling requirements to prevent degradation before installation.
Selection Notes
Select this component when high isolation voltage is required in a standard DIP footprint. Consider the specific current transfer ratio requirements for the application. Evaluate thermal management needs given the operating temperature range. Verify that the pinout matches the target PCB design constraints.
Part Context
This part belongs to the CNY17 series of optocouplers from Fairchild Semiconductor. The series includes variants like CNY17F1, F2, and F3, differentiated primarily by current transfer ratio bins. The CNY17F4300W represents a specific binning or packaging variant within this family, utilizing the same core optoelectronic structure.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the part is marked obsolete, engineers should consult manufacturer cross-reference guides or equivalent generic transistor-output optocouplers with matching isolation ratings and pin configurations.
