Working Principle

The PC815XPJ000F is the combination of an infrared LED and a detector. The infrared LED is driven by an external voltage source that provides the current to light up the LED internally. The light generated is proportional to the input current. The detector, on the other hand, converts the light to current. This is done by a photovoltaic effect, meaning the light from the LED is used to generate a voltage across the output of the detector. The output of the detector is proportional to the input current and therefore the signal is transmitted from the input to the output.

Conclusion

The PC815XPJ000F is an optoisolator that uses a transistor–photovoltaic output for signal transmission and high-voltage isolation. The component offers a number of features and applications in a variety of industries. Its operation is based on the principle of combining an infrared LED and a detector, where the detector converts the light from the LED to current through a photovoltaic effect.
