Optoisolators, also called optocouplers, are optical components designed to isolate electrical circuits. Specifically, optoisolator-type devices utilize an LED on one side of the optoisolator to modulate light to a photodiode or photovoltaic device, forming a reference voltage, which is isolated from the main circuit. The 6N136#500 is a type of transistor version optoisolator with a photovoltaic output. It is one of the most popular optoisolators due to its robust performance and long lifetime.

6N136#500 Optoisolator Features

The 6N136#500 optoisolator is a 3-terminal device that features a dual-way structure with a photovoltaic output. It is constructed with an LED light source that produces a continuous or modulated light depending on the operating parameters. The light produced is then sensed by a photodiode which in turn creates a reference voltage that is isolated from the main circuit. In addition, the 6N136#500 optoisolator features a high-voltage AC-DC off switch, which is an additional layer of electrical isolation for the main circuit. The optoisolator also offers low power consumption and fast photo-detection time.

6N136#500 Optoisolator Working Principle

The 6N136#500 optoisolator is based on a voltage driven electrical circuit principle. Essentially, when electrical power is applied to the input of the optoisolator, a current passes through the LED which causes it to illuminate. The light that is produced by the LED then passes through an optically-isolated path and reaches a photodiode. The photodiode receives the light and produces a reference voltage, which is isolated from the main circuit. The moment the reference voltage is equal to the input voltage, the circuit switches off, thus preventing any further current from passing through.

6N136#500 Optoisolator Application Fields

The 6N136#500 optoisolator is used in a wide range of applications due to its small size, reliable isolation and long lifetime. It is mainly used in signal transmission applications, for example, to provide electrical isolation between power supplies, microcontrollers and signal sources. Additionally, it can be used as a switch element in a relay circuit, a current controller in AC motors and a gate driver in FET/IGBT circuits. The optoisolator is also frequently used in telecommunications and data communication devices, where a reliable and secure electrical isolation is needed.

Conclusion

The 6N136#500 optoisolator is an ideal choice for applications requiring a reliable and safe electrical isolation. It has a dual-way structure, low power consumption and a long lifetime. Additionally, it features a high-voltage AC-DC off switch which provides additional layer of electrical isolation for the main circuit. The optoisolator is used widely in signal transmission, data transmission, telecommunications, current controllers and gate drivers.
