Optoisolators, also known as optocouplers, are devices that transfer electrical signals between two isolated parts of an electrical system. The 6N139#500 is a type of Photovoltaic Output optoisolator that can be used in various applications. This article will provide an overview of the 6N139#500’s applications and working principle.

Application Field of 6N139#500

The 6N139#500 optoisolator is a 4 channel device which is commonly used in isolation, conversion, and stabilization applications. It can be used to transfer power from a low or line voltage application to an isolated circuit. It is well suited for data signal isolation in order to prevent the leakage of noise currents. The 6N139#500 can also be used for Data Communications, Power Supply, Noise Filtration, and Voltage Regulation.

The 6N139#500 optoisolator is particularly useful in applications where there is a risk of ground loops. These are most commonly caused by having multiple grounds in parallel or when two parts of an electrical system that are connected together have different ground levels. By using the 6N139#500, any voltage differences between the two parts of the system can be minimized. This will reduce the risk of damaging components or causing the system to malfunction.

Working Principle of 6N139#500

The 6N139#500 optoisolator works on the principle of photoconductivity. Photoconductivity occurs when light is shone onto a semiconductor material. This causes electrons to be released, which in turn affects conductivity. In the case of the 6N139#500, the photoconductive element is a light-emitting diode (LED) which when excited by a current, emits light with a specific wavelength. This light then passes through a light-sensitive transistor, which controls current flow. When the 6N139#500 is used in isolation applications the LED and the transistor are contained in two metal cans separated by a thin slice of insulating material. This prevents any electrical connection between the two parts, while ensuring that data signals can be transferred between them.

The 6N139#500 optoisolator has several advantages. It is fast and reliable, and it has high common mode rejection, which means that it can filter out any noise signals from the circuit. It also has a wide range of applications across a range of industries and can be used in various temperature conditions, making it suitable for a wide variety of applications.

In conclusion, the 6N139#500 optoisolator is a type of Photovoltaic Output optoisolator which can be used in isolation, conversion, and stabilization applications. It is suitable for a wide range of applications, including data signal isolation, data communications, power supply, noise filtration, and voltage regulation. It works on the principle of photoconductivity, with a LED and light-sensitive transistor contained in two metal cans and separated by an insulating material. It has several advantages, which makes it a versatile and reliable device that can be used in a wide range of conditions.
