Optoisolators are designed to provide electronic isolation between two separate circuits using an LED and a phototransistor as the active components. The CNC1S171R0LF part is no exception to this idea. It can provide high immunity to NF signals, and has an output current that can vary from 0.2 to 6.0 mA, depending on the LED bias current.

Application field of CNC1S171R0LF

CNC1S171R0LF has a wide range of usage. Its phototransistor has fast response time that is suitable for high switching frequencies. It is applicable for isolating digital signals in applications where signal integrity or optical noise immunity is important, such as UPS, industrial automation and alarm systems. Additionally, CNC1S171R0LF is a generic optocoupler that meets the basic requirements of electrically powered equipment, thereby making it applicable to industrial controls, temperature controllers, and home appliances.

Working Principle of CNC1S171R0LF

CNC1S171R0LF consists of an LED and a phototransistor. A LED is responsible for emitting light, while a phototransistor works as a light to electrical signal converter. The signal to be isolated is applied to the LED’s anode, thereby causing it to emit light. This light is converted into an electrical signal by the phototransistor, which is then used as the isolated output. The LED’s cathode is connected to the phototransistor’s base. Since both devices are mounted in an insulated package, they are completely isolated from each other.

Conclusion

CNC1S171R0LF is an ideal choice for applications requiring signal isolation. It is known for its fast response time, optical noise immunity, high switching frequency and variable output current. Moreover, it is applicable for controlling industrial equipment, home appliances, and temperature controllers. All in all, CNC1S171R0LF has a wide application range and is an ideal choice for applications with stringent noise immunity requirements.
