Description

The CNY17-3 optocoupler consists of an infrared light-emitting diode (LED) on the input side and a silicon phototransistor on the output side. When the input LED is forward biased, it emits infrared light, which is detected by the phototransistor, causing it to conduct and allowing the signal to pass from input to output while maintaining electrical isolation.

Features

  • Electrical Isolation: Provides high isolation voltage between input and output, typically rated up to 5000 VRMS, ensuring protection of low-voltage circuits from high-voltage spikes.
  • Standard DIP-6 Package: Encased in a standard 6-pin DIP package for easy handling and installation in printed circuit boards (PCBs).
  • High Current Transfer Ratio (CTR): Offers a high current transfer ratio, ensuring efficient signal transmission.
  • Low Input Current: Operates with low LED input current, enhancing energy efficiency.
  • Wide Compatibility: Interfaces easily with both TTL and CMOS logic levels.
  • Reliable and Durable: Known for its stability and durability in various operating environments, making it suitable for industrial and commercial applications.

Specifications

  • Input LED Forward Voltage: Typically 1.2V (maximum 1.4V) at 10mA forward current.
  • Input LED Reverse Voltage: Maximum 6V.
  • Isolation Voltage: 5000 VRMS.
  • Current Transfer Ratio (CTR): Typically 100% to 200% at IF = 10mA, VCE = 5V.
  • Collector-Emitter Voltage (VCEO): Maximum 70V.
  • Collector Current (IC): Maximum 50mA.
  • Collector-Emitter Saturation Voltage (VCE(sat)): Maximum 0.3V at IC = 2mA, IF = 10mA.
  • Response Time:
    • Rise Time (tr): Typically 3µs.
    • Fall Time (tf): Typically 5µs.
  • Operating Temperature Range: -55°C to +100°C.

Applications

  • Signal Isolation: Used to isolate high-voltage sections from low-voltage sections in electronic circuits.
  • Power Supplies: Commonly used in switch-mode power supplies (SMPS) to provide feedback from the output side to the control side while maintaining isolation.
  • Microcontroller Interfacing: Isolates microcontrollers from high-voltage components, preventing damage and interference.
  • Motor Control Circuits: Protects low-voltage control electronics from high-voltage motor drivers.
  • Industrial Automation: Provides isolation and protection in sensor systems, control units, and data communication interfaces.
