VO1263AAC

Optoisolators, also known as voltage opto-couplers, photocouplers or optical isolators, are optoelectronic components that electrically isolate signals from the input to the output and protect the output device from voltage surge and ground loop interference. The VO1263AAC optoisolator is classified as a Transistor, Photovoltaic Output optoisolator.

The VO1263AAC optoisolator is designed to provide electrical isolation in timing circuits, light sensing, as well as audio and video switching applications. It has an LED input stage which is coupled to a Darlington transistor output stage. The LED has a voltage drop of 1.6V, and the average current which it carries is 10mA. The transistor output stage has a maximum collector voltage of 40V and a maximum collector current of 50mA.

The working principle of the VO1263AAC optoisolator is based on the photo-voltaic effect. When an electrical current passes through the LED, the semiconductor absorbs the energy and releases photon particles. These particles are then absorbed by the photovoltaic cell which generates a small electricity that triggers the Darlington transistor. The Darlington transistor then conducts electrical current to output the optoisolator’s signal.

The VO1263AAC optoisolator is ideal for applications that require electrical isolation between the input and the output, such as in switching electronics, signal amplification, and protective circuits. It is also suitable for applications that require low power and current, such as audio and video switching applications. Furthermore, since it is a rugged and reliable device, it is also suitable for long-term usage in a harsh environment.

In summary, the VO1263AAC optoisolator is a Transistor, Photovoltaic Output type optoisolator that provides electrical isolation for timing circuits, light sensing, as well as audio and video switching applications. Its working principle is based on the photo-voltaic effect and the average current it carries is 10mA. It is a reliable and rugged device that is suitable for long-term usage in harsh environments.
