Optoisolators are used to electrically isolate two circuits while allowing them to exchange information through light. SFH608-4X001 is one type of optoisolators, and it belongs to the photovoltaic output transistor type. This section will discuss its application field and working principle.

Application Field

SFH608-4X001 optoisolators are used in a variety of applications. The most common are: level conversion, isolating a signal from noise, power line communication, and voltage monitoring. It can also be used to isolate digital signals and isolate analog and digital signals from each other. In addition, it is suitable for monitoring the load current and motor speed of industrial control equipment.

Working Principle

SFH608-4X001 optoisolator works on the basis of the photo-sensitivity principle. Firstly, it contains an infrared LED, which when energized, produces infrared light beam. When the light beam is absorbed by a photosensitive material, it generates a flow of electrons that is converted into a voltage. On the other side, it also contains a transistor, which has two terminals, the collector terminal and the emitter terminal. When the voltage generated from the photosensitive material reaches the critical point, it will turn on the transistor, and current is able to flow from the collector to the emitter.

This optoisolator thus works on the principle of optoelectronic conversion. The infrared light from the LED is converted into voltage by a photosensitive material, which is then used to turn on the transistor. When the transistor is turned on, current is able to pass from the collector to the emitter, and the two circuits are electrically isolated, while still being able to exchange information through light.

Conclusion

SFH608-4X001 optoisolators are an important type of optoelectronic isolation devices, and are used for many applications, such as level conversion, noise isolation, power line communication, and so on. It works on the principle of optoelectronic conversion, where an infrared LED is used to generate a light beam, which is then converted into voltage by a photosensitive material. This voltage is used to turn on a transistor, allowing current to flow from the collector to the emitter, thus electrically isolating the two circuits and allowing them to exchange information through light.
