Description

The CNY17-4 optocoupler consists of an infrared light-emitting diode (LED) on the input side and a silicon NPN phototransistor on the output side. When the LED is forward biased, it emits infrared light that is optically coupled to the phototransistor. The phototransistor then switches on, allowing current to flow and transmitting the signal from input to output while maintaining electrical isolation.

Features

  • High Electrical Isolation: Provides electrical isolation between input and output, typically rated up to 5000 VRMS, ensuring protection against high voltage surges.
  • Standard DIP-6 Package: Encased in a 6-pin DIP package, which is easy to integrate into various circuit designs.
  • High Current Transfer Ratio (CTR): Offers a higher CTR compared to other variants in the CNY17 series, ensuring efficient signal transmission.
  • Low Input Current Requirement: Operates efficiently with low LED input current.
  • Wide Compatibility: Can interface with both TTL and CMOS logic circuits, making it versatile for digital applications.
  • Reliable Performance: Stable and durable performance across various operating environments.
  • Open-Collector Output: Allows for flexible interfacing with different types of loads and circuits.

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 160% to 320% 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: Commonly used to provide isolation between high-voltage and low-voltage sections of a circuit.
  • Switching Power Supplies: Used to isolate feedback signals from the high-voltage side to the low-voltage control side.
  • Microcontroller Interfacing: Protects microcontrollers from high voltage circuits, ensuring safe operation.
  • Motor Drive Circuits: Protects control electronics from the high-voltage and noise generated by motor drivers.
  • Industrial Automation: Widely used in sensors, control systems, and communication interfaces to maintain signal integrity and protect equipment.
