Optoisolators - Logic Output

An optoisolator, also known as an optocoupler is an electronic component designed to provide electrical isolation between two circuits, usually a signal and a power circuit, while allowing them to communciate. One of the most popular optoisolators in the market is the Fairchild 6N137SVM. This article focuses on its application field and working principle.

Application Field

The 6N137SVM optoisolator provides an effective solution for alleviating the effects of high voltage spikes caused by transients and line surges. Its general purpose, features and cost make it the preferred solution for issues related to interference with digital signals, such as noise, glitches and crosstalk. It provides superior performace when isolating high frequency signals from one circuit to another, and many other I/O applications.

Working Principle

The 6N137SVM optoisolator consists of an LED and a photosensitive element. The LED emits light when a small current flows through it, and the photosensitive element detects changes in the light intensity. When the LED is on, the optoisolator is in a conductive state and the current between the two circuits is allowed to pass. When the LED is off, the optoisolator is in a non-conductive state and the current between the two circuits is blocked.

The 6N137SVM optoisolator provides a high degree of electrical isolation between the two circuits (as high as 3000 Vrms). It also has a high operating temperature range, making it suitable for use in high-temperature environments. It is also resistant to vibrations and shocks, making it suitable for use in applications such as aerospace or automotive applications.

The 6N137SVM optoisolator also has a low power consumption, making it suitable for battery powered devices. Furthermore, it is RoHS compliant, making it an environmentally-friendly solution for applications such as industrial automation, medical devices, etc.

Conclusion

The 6N137SVM optoisolator is an ideal solution for providing electrical isolation between two circuits while allowing them to communciate. Its features and cost makes it the preferred solution for a variety of applications such as industrial automation, medical devices, aerospace and automotive applications. The 6N137SVMoptocoupler offers a high degree of electrical isolation, as well as high operating temperature, resistance to shock and vibrations, low power consumption and environmental compliance.
