Optoisolators are electronic components that use light as a form of isolation between two circuits. The 6N139WV is a type of optoisolator, specifically a translator with transistor photovoltaic output. It is designed to provide insulation between input and output, protecting not only the equipment but also personnel. This article will provide a brief overview of the 6N139WV\'s application fields and workings principles.

In terms of applications, the 6N139WV is popularly used to control switching being used as an input device in various applications such as circuit, remote control of motor drivers, as well as controlling relays and solenoids. When used in such applications, the 6N139WV isolates the input signals from the output load, reducing the chances of leakage or interference occurring. The 6N139WV also has a wide voltage range, and it can operate in temperatures from -55°C to 125°C. It is also designed to be a fast device, responding to signal changes in 1.5µs.

Another application of the 6N139WV is in Sensors that require insulation and linear or analogue signals. Its opto coupler, low propagation time, wide supply voltage range and high sensitivity allows for accurate and reliable sensing of temperature and current signals, without requiring compromises in performance or accuracy. It is also suitable for position, angle and temperature measures, as well as linear velocity measures, in robotic, automotive, medical and other systems where isolation and reliable tracking are necessary.

The 6N139WV is so reliable because it operates using the principle of photo voltaic output. At its core are a Led (light emitting diode) and an NPN transistor, along with a base resistor. The 6N139WV works by emitting light with the Led, which is then processed by the transistor, resulting in a corresponding electrical signal being generated at the output. The isolation of the input signal is done at a purely optical level, providing a high level of protection and accuracy.

The 6N139WV also has its own setting and operation characteristics that make it stand out. Since it eliminates the need for external components, it requires minimum space on a printed circuit board (PCB). It also has a relatively low maximum operating temperature of 125°C, and a wide supply voltage range (from 4.5V to 40V), making it very flexible to use in different applications. Finally, its high mechanical durability also allows for long-term use, making the investment worthwhile.

In conclusion, the 6N139WV is a type of transistor photovoltaic output optoisolator. It is used in various applications to provide reliable and accurate insulation between input and output, such as in controls, relays, sensors, and other systems where isolation is necessary. The optoisolator operates using the principle of photo voltaic output, using a Led and NPN transistor, and it also has its own characteristics such as its low maximum operating temperature, wide voltage range, small overall size, and high durability. Its reliable performance makes it suitable for many applications, and its cost effectiveness allows for long-term use.
