CNY117F-2X001

Optoisolators - Transistor, Photovoltaic Output

The CNY117F-2X001 is a high-difficulty optocoupler composed of a GaAlAs LED and phototransistor coupled together inside a single housing. An optocoupler, also referred to as a photocoupler or optoisolator, is a commonly used device in the development of electronic control systems and is used to provide electrical isolation between circuits. Compared with its standard CNY17 series, CNY117F-2X001 has a lower current drive, higher CTR, and higher isolation voltage.

Application Field

The CNY117F-2X001 is commonly used for DC motor control applications, verification of transmitted data, and controlling the on & off of light switches within electronic circuits, such as ballasts; and it is even used in industrial controller systems. It can also be used for safety-related applications, as its high isolation voltage of up to 5kVAC ensures that interference or breakdown failure will not occur, which will result in a failure of the entire system if not taken into consideration. Moreover, its small size makes it ideal for applications where space is an issue.

Working Principle

The CNY117F-2X001 uses a LED and phototransistor as its main components. The LED is the light source, and the phototransistor is the device that detects the light. When a voltage is applied to the LED, the LED will produce light that is detected by the phototransistor. The phototransistor then generates a current that is in proportion to the intensity of the light. The current generated by the phototransistor can then be used to control various electrical components, such as a transistor. This controlling of components helps to both identify and amplify signals from an input circuit.

Conclusion

The CNY117F-2X001 is an optoisolator that is designed to provide electrical isolation between circuits, which makes it ideal for use in a variety of applications. Its high CTR and isolation voltage makes it useful for safety-related applications, and its small size makes it ideal for applications where space is a concern. Understanding its application field and working principle makes it easier for engineers to take advantage of its features and incorporate it into the design of their circuit.
