Overview
The CNY17G-3 is a single-channel optocoupler featuring an infrared emitting diode and an NPN phototransistor with base terminal. It provides 5000Vrms isolation voltage in a 6-DIP package. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a forward current of 60mA, and a typical forward voltage of 1.65V. The current transfer ratio ranges from 100% to 200% at 10mA input. Switching characteristics include typical rise and fall times of 2µs.
Feature Summary
- Integrated base terminal on the NPN phototransistor for improved switching speed and linearity
- High isolation voltage capability of 5000Vrms for robust signal transmission
- Wide operating temperature range suitable for industrial environments
Applications
- Signal isolation in microprocessor systems
- Solid-state relay driver circuits
- Logic level translation between different voltage domains
Procurement Notes
Verify the specific suffix G against the manufacturer datasheet to confirm insulation system compliance and regulatory approvals. Ensure the ordering part number matches the required current transfer ratio bin. Confirm package dimensions and pinout compatibility with the target PCB footprint before procurement.
Selection Notes
Select this component when base-driven output is required for faster response compared to standard phototransistors. Verify that the 5000Vrms isolation rating meets the safety requirements of the application. Check that the 100-200% CTR range aligns with the drive circuit design constraints.
Part Context
This component belongs to the Vishay CNY series of transistor-output optocouplers. It shares the same physical package and basic electrical structure as other variants in the family, differing primarily in the current transfer ratio binning and specific insulation certification markings.
Replacement Considerations
Direct substitutes include CNY17-3 and CNY17-4, provided the specific current transfer ratio requirements are met. Verify that replacement parts maintain the same 6-DIP package and isolation voltage ratings.
