HCNW136-300E Application Field and Working Principle

Optoisolators, also known as optocouplers, are electronic components with a built-in optoelectronic device that enables isolated electrical isolation between two circuits. The optoelectronic device is essentially a combination of a light-emitting diode (LED) and a light-sensitive component (e.g., a photodiode or phototransistor) sealed in a single housing. The HCNW136-300E is a type of optoisolator belonging to the transistor, photovoltaic output family. These optoisolators have a photovoltaic device as the output, rather than a transistor or Schmitt trigger. The output of the photovoltaic device is proportional to the input LED intensity, which is determined by the drive voltage. The HCNW136-300E optoisolator can be used in various applications such as protection, level shifting, amplifying, signal isolation, and more. Its main features include a wide range of input-output isolation ranges, high surge rating, and extremely long life.

Working Principle

The working principle of an optoisolator generally involves two parts: the input side and the output side. In the case of the HCNW136-300E, which is a transistor, photovoltaic output optoisolator, electroluminescence is generated when a forward-biased LED is illuminated when an AC or DC voltage is applied across it. This LED is the “input side” of the circuit. The light from the LED is coupled to a photodetector, such as a photodetector, photodiode, or phototransistor, through the transparent window of the housing. This is the “output side” of the circuit. When the LED is illuminated, the photodetector produces a proportional output current. This current is then fed to a transistor or Schmitt trigger, the output of which is the optoisolator’s final output. The output of the HCNW136-300E optoisolator is proportional to the input LED intensity, which is determined by the drive voltage.

Conclusion

The HCNW136-300E optoisolator is an important component in applications that require electrical isolation between two circuits. Its wide range of input-output isolation ranges, high surge rating, and long life make it a very valuable component. By understanding the working principle of the HCNW136-300E, one can better understand its applications and take advantage of its features.
