Overview
The CNY66B is a high-speed phototransistor optocoupler featuring an infrared-emitting GaAs LED paired with a silicon phototransistor. It offers a collector-emitter voltage of 55 V and a collector current rating of 50 mA. The device provides a current transfer ratio of up to 125% at 5 mA forward current. Isolation voltage is rated at 5,000 Vrms for one minute. The component operates within a temperature range of -40°C to +100°C and utilizes a DIP-4 package.
Feature Summary
- High-speed switching capability suitable for data transmission applications
- Integrated guard ring structure between emitter and detector reduces stray capacitance
- RoHS compliant construction without halogenated flame retardants
Applications
- Data communication equipment
- Industrial control systems
- Signal isolation circuits
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct packaging and lead time specifications. Confirm that the requested variant matches the required isolation voltage and current transfer ratio parameters defined in the datasheet before finalizing procurement orders.
Selection Notes
Select this component when high-speed signal isolation is required in compact DIP packages. Ensure the application circuit accounts for the specified current transfer ratio variations across temperature ranges. Verify that the input forward current and output load conditions remain within the absolute maximum ratings provided in the electrical characteristics table.
Part Context
This device belongs to Vishay's CNY66 series of high-speed optocouplers designed for efficient signal transfer with minimal delay. The series includes variants with different current transfer ratios and packaging options. The CNY66B specifically targets applications requiring reliable isolation with fast response times in industrial and communication environments.
Replacement Considerations
Direct replacements must match the DIP-4 package, 55V Vceo, and similar speed characteristics. Verify pinout compatibility and isolation voltage ratings. Consult official cross-reference lists for confirmed substitutes from the same manufacturer or approved equivalents with identical functional specifications.
