Optoisolators, also known as optical couplers, are electronic components which use optical signals to electronically isolate two environment, providing a level of electrical isolation between input and output circuits. Transistor Photovoltaic Output solutions, such as the SFH6135-X006, are available for a number of electronic applications. This article will explore in detail the application fields and working principles of the SFH6135-X006.

Application Fields

The SFH6135-X006 solution finds a great number of application fields, ranging from industrial and household usage to the automotive and medical spaces. Some of the key examples include, but are not limited to:

• Light sensitive switch for industrial applications
• Infrared receiver for consumer electronics
• Infrared emission control for automotive purposes
• Circuit isolation between medical equipment

Due to its space-saving design, the SFH6135-X006 can be used in portable devices which require reliable isolation.

Working Principle

The SFH6135-X006 from OSRAM is an example of a photovoltaic output device, meaning that it receives electrical input in the form of light and produces a high-isolation digital output. It is built with an LED coupled to an optically isolated phototransistor internal to the same package. When no light is received, the state of the output is a high-impedance state. When exposed, the operational phototransistor turns on and the output goes low. This switching behavior is also known as optical coupling, meaning it is fully isolated from both the input signals and the output.

The key characteristics that make the SFH6135-X006 perfect for the application fields discussed above are its small size, low power consumption, and high speed. As it is a 4-pin device, it can also be used in packages which require small footprints.

Conclusion

The SFH6135-X006 optoisolator is a great example of the transistor photovoltaic output family, delivering high-isolation digital output with low power consumption. It finds application in areas ranging from industrial to automotive, making it a great solution for portable devices and space-saving packages. With its characteristics and capabilities, it is a great choice for a variety of applications.
