Overview
The CNY66 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates an NPN phototransistor with a gallium arsenide infrared-emitting diode in a 4-DIP package. Key electrical parameters include a maximum collector-emitter voltage of 32 V, a collector current rating of 50 mA, and a saturation voltage of 300 mV. The device offers a high isolation voltage of 8200 Vrms and supports a forward current up to 75 mA. Current transfer ratios range from 50% to 300% at 10 mA input.
Feature Summary
- Provides very high isolation voltage capability for safety-critical applications
- Features a standard 4-pin plastic DIP package for through-hole mounting
- Integrates a phototransistor optically coupled to an infrared-emitting diode
Applications
- General-purpose signal isolation
- Microprocessor system interfacing
- Logic circuit isolation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and compliance status. Confirm that the component meets RoHS3 requirements if applicable to your design constraints. Cross-reference the part number with authorized distributors to validate authenticity and availability before finalizing procurement decisions.
Selection Notes
Select this component when high isolation voltage is required alongside standard transistor output characteristics. Ensure the operating temperature range of -55°C to 85°C aligns with environmental conditions. Verify that the 32 V collector-emitter voltage and 50 mA collector current limits are sufficient for the intended load requirements.
Part Context
The CNY66 belongs to the CNY64/CNY65/CNY66 series of Vishay optocouplers. These devices share similar structural designs but may differ in specific electrical ratings or testing criteria. This series is designed for general-purpose isolation tasks requiring reliable performance in compact packages.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements may not match the 8200 Vrms isolation rating or specific current transfer ratio ranges.
