Optoisolators, also known as optocouplers, are components used for electronic isolation that help provide protection from electrical noise, overvoltage, and transients. An optocoupler typically consists of an infrared LED and a photovoltaic photo-detector that are electrically isolated from each other in two different circuits. In this article we discuss the application field and working principle of the PS2811-1-F3-A optocoupler.

The PS2811-1-F3-A optocoupler consists of an infrared LED and a photovoltaic photo-detector which provide high common-mode transient immunity (CMTI) and isolation voltage. This optocoupler is widely used in the industrial automation and semiconductor fields. It can be used in a variety of different applications, such as digital and logic signal isolation, level sensing, and low-level SMPS power supplies.

The PS2811-1-F3-A optocoupler consists of an infrared LED coupled with a photovoltaic photodetector. The LED emits infrared light when a current is applied and the photodetector converts this light into electrical energy. This electrical energy is then used to operate an output transistor which provides isolation between two electrical circuits. The output transistor has a relatively low turnout current, making it ideal for digital and logic signal isolation applications.

The PS2811-1-F3-A optoisolator is capable of providing a high level of isolation voltage up to 5,000 VRMS. This allows it to be used in a variety of different applications including isolated communication links, protection circuits, and medical instrumentation. Additionally, the PS2811-1-F3-A optocoupler provides a wide common-mode transient immunity (CMTI) range from 10 kV/µs to 50 kV/µs. This helps to ensure reliable signal transfer between two electrical circuits.

The working principle of the PS2811-1-F3-A optoisolator is relatively simple. When a current is applied to the LED, it emits infrared light. This light is detected by the photodetector, which then converts it into electrical energy. The electrical energy is then used to operate the output transistor, allowing for isolation between two electrical circuits.

Overall, the PS2811-1-F3-A optoisolator is an important component for providing electrical isolation between two circuits. It has a wide range of applications, such as digital and logic signal isolation, level sensing, and low-level SMPS power supplies. Additionally, the high level of isolation voltage and common-mode transient immunity (CMTI) offered by this optoisolator make it an ideal option for a variety of applications. Finally, the working of the optoisolator is relatively simple: an infrared LED is coupled with a photovoltaic photodetector, and this detects the light and converts it to electrical energy to operate an output transistor.
