The 6N137-V optoisolator is part of a family of industry leaders in the opto couplers and isolators market. It is actively used for applications in industrial, medical, and commercial markets. The 6N137-V belongs to the Optoisolators - Logic Output category, because of its opto-electrical integrated circuit design that consists of LED, phototransistor and a series of components that provide isolation and protection from external disturbances.

The 6N137-V provides complete insulation from input to output connections, allowing it to be used in a variety of high voltage or ground loop circuit designs. It has excellent coupling efficiency, an operating temperature range from -65°C to +125°C, and a storage temperature range from -65°C to +150°C which makes it ideal for a wide range of environments.

An important feature of the 6N137-V is its 6 Volt input threshold and logic level output. This feature makes it a very useful device for many logic level applications. Applications of the 6N137-V include low to medium current switch control; logic level applications; and power supply isolation.

The working principle behind the 6N137-V lies in the opto-electrical integrated circuit design. A LED is used as the light source with a phototransistor as the electrical output. The logic level input voltage is applied to the LED, which in turn generates an optical output. The light is then detected by the phototransistor which generates the logic level output and provides complete isolation between input and output.

The 6N137-V contains other components to further provide isolation. To prevent electrical disturbances from influencing the output of the device, a Zener diode is connected between the LED and the phototransistor. Additionally, a capacitor is connected across the phototransistor to ensure stability and reduce the risk of electrical disturbances.

The 6N137-V is designed to meet international safety standards and has UL, CUL and CSA certifications. Its combination of high isolation, excellent coupling efficiency and its wide range of features make it an ideal choice for a variety of circuit designs.
