Optoisolators are electronic components designed to provide electrical isolation between two parts of a circuit when switching or controlling a high power current. The 6N139-520E optoisolator is a TPO (transistor, photovoltaic output) type optoisolator designed for use in applications such as industrial control, computer, process control, and other areas where a high amount of electrical isolation is required. In this article, we will discuss the application fields and working principle of the 6N139-520E.

Application Field: The 6N139-520E optoisolator is well suited for use in applications where space is limited, such as in narrow enclosures. It has a standard closed loop gain of 8 V·s at 1 kHz and a current transfer ratio (CTR) of 1.5 A/mA. The device can be used to isolate switch contacts in emergency stoppage systems, for logic signal isolators, and for signal and power isolation. It is also well suited for use with industrial DC PLCs and AC/DC servo motors, as well as computers, process control, and other applications where an isolated output is required.

Working Principle: The 6N139-520E optoisolator works by employing a photovoltaic (PV) effect to create electrical isolation between two different segments of a circuit. Light-generated electrons and holes are created in the device when the base of the optoisolator is illuminated by an external light source such as an LED. When this occurs, a reverse voltage is created across the device, causing a current to flow. This current is then able to flow through the collector/emitter junction of the device, creating an open collector output signal that can be used to control or switch a high power current. Additionally, the noise created in the output side of the optoisolator is suppressed by the internal diode and capacitor network.

In conclusion, the 6N139-520E optoisolator is a TPO (transistor, photovoltaic output) type optoisolator widely used for electrical isolation of logic signals in industrial, computer, process control, and other applications. The optoisolator works by employing a photovoltaic effect to create an open collector output signal that can be used to control or switch a high power current. Additionally, the noise created in the output side of the optoisolator is suppressed by the internal diode and capacitor network.
