Working Principle

The PC6N139X works by incorporating both a photovoltaic flight and a PN junction. The photovoltaic diode, also known as an opto-isolator, is a component which utilizes light in order to provide electrical isolation between two circuits. The PN junction is a type of semiconductor device, or diode, which consists of a positive and negative terminal. The photovoltaic diode absorbs light and generates an electric current, which then flows through the PN junction. The PN junction in this optoisolator utilizes both the positive and negative terminals to generate a current when exposed to light.

The PC6N139X also utilizes a transistor output, which is used for further isolation. The transistor in this optoisolator acts as a switch, controlling the flow of the current generated through the PN junction. The transistor is activated when the photovoltaic diode receives light, allowing the current generated by the PN junction to output on the collector terminal of the transistor. The transistor also prevents any electrical signals from leaking out of the optoisolator, providing additional protection and safety.

Conclusion

The PC6N139X optoisolator utilizes a photovoltaic flight and a PN junction, as well as a transistor output, to provide electrical isolation and safety between two circuits. The PC6N139X has a wide range of applications ranging from medical, electrical, automotive, and communication industries. The photovoltaic diode of the PC6N139Xabsorbs light and creates an electric current which is then regulated by the PN junction. The transistor of the PC6N139X provides additional safety and isolation to prevent any electrical signals from leaking from the optoisolator.
