Working Principle

The overall working principle of the HCNW135-500E optoisolator is fairly straightforward. It features an integrated phototransistor that is used to detect incoming electrical signals. When the phototransistor senses the signal, it triggers a light-emitting element like a LED and this in turn triggers the phototransistor at the other end. This creates the galvanic isolation that makes the device so useful in many different types of applications.

The optoisolator also works on the principle of optical feedback, which allows it to provide a high level of electrical isolation with low losses in an inexpensive and reliable package. The optical feedback circuit consists of two phototransistors that are separated by a light-emitting element. When the circuit detects a signal, it will cause the LED to emit light, which is then detected by the phototransistor at the other end and the signal is repetitiously transmitted.

This optoisolator also offers a wide range of performance options depending on the specific application. It offers a wide range of insulation volatages from 260 VAC to 30kVAC, with the efficiency of the device also increasing with voltage. In addition, it can operate at temperatures of up to 105°C and can withstand surges up to 3.0V.

Conclusion

In conclusion, the HCNW135-500E optoisolator is a highly versatile device that offers a range of features that make it suitable for many different types of applications. It offers a phototransistor input, a 4-pin leaded package, and a wide range of insulation voltage and temperature options.
