Optoisolators are components designed to allow signals from a controller to interface a wide range of output devices. The 6N137-500E is an optoisolator from NVE Corporation that is applied in logic-level output applications. This optoisolator improves signal isolation while providing a common-mode transient immunity of up to 25kV/μs.

Design Summary

The 6N137-500E is a 6-pin DIP optoisolator. This optoisolator is intended for use in low-power, TTL compatible applications. It consists of a gallium arsenide infrared LED on one side, and an NPN silicon phototransistor on the other side. The packaging of the optoisolator is optimized to make the phototransistor active under all normal operating conditions in order to ensure a predictable and reliable performance.

Applications

The 6N137-500E is ideally suited for logic-level output applications. It has a large amount of isolation between the input and output of the device and provides a high degree of electrical protection. The 6N137-500E can also be applied in industrial systems, providing isolated communication signals, as well as in voltage-level shifting applications.

Working Principle

The working principle of the 6N137-500E relies on its two main components – the gallium-arsenide LED and the NPN phototransistor. The signal is coupled optically between these two components, thereby providing electrical isolation between the input and output stages. When the LED is electrically energized, it emits a light beam which is gathered and converted into an electrical signal by the phototransistor. The phototransistor is then used to drive a load. Moreover, the 6N137-500E features an additional electric shield which helps to block out the noise generated by the LEDs and the phototransistors, thus preventing any sound interference.

Features

NVE Corporation’s 6N137-500E optoisolator offers a number of features to its users. These features include a low-current logic-compatible output, high-speed operation up to 5Mbps, a wide-range input voltage operating from 4.5V to 16V, a guaranteed common-mode transient immunity of 25kV/μs and a logic-high output voltage of 2.25V or higher. The 6N137-500E also has a robust design, which allows for a reliable performance in the toughest of environments.

Conclusion

The 6N137-500E optoisolator from NVE Corporation is an ideal choice for logic-level output applications requiring reliable electrical signal isolation between two circuits. This optoisolator provides a wide operating voltage range and a wide-ranging electrical noise rejection. The 6N137-500E also provides a guaranteed common-mode transient immunity of 25kV/μs, which provides enhanced protection against any electrical surge.
