Optoisolators - Transistor, Photovoltaic Output

OPIA801DTU Application Field and Working Principle

The OPIA801DTU, marketed by Shanghai OptoElectronic Co., Ltd, is a type of optoisolator that consists of an infrared light-emitting diode (LED) coupled with a photodiode. It serves as an isolation barrier between electronic circuits and is used to transfer electric signals from one circuit to another with complete electrical insulation. This device is designed for application in a wide range of industrial, medical, and automotive electronic systems.Optoisolators are used in applications where two separate circuits are required to conduct electrical communication, but are also functionally isolated from each other. The requirement for isolation eliminates the possibility of any electrical connection between the two circuits. The OPIA801DTU takes advantage of the physical property of light, which will not cross circuit boundaries. As a result, one circuit can be completely electrically isolated from the other while still being able to transmit a signal between them. The working principle of the OPIA801DTU consists of two distinct circuits: a “transmitter” and a “receiver”. The transmitter is composed of a light source, such as an LED, while the receiver is composed of a photosensor. When an electrical signal is applied to the LED, it generates light. This light passes through an optical path and is then detected by the photosensor on the other side. This signal is then converted into an electrical output.The OPIA801DTU is designed to have low signal propagation delay, allowing for fast transmission of signals. As a result, it can be used in a wide variety of applications requiring isolation, such as industrial controls, medical systems, and automotive systems. This device also features high common mode rejection ratio, wide power supply voltage range, adjustable gain, and low EMI. All of these features make the OPIA801DTU a versatile optoisolator and a convenient choice for any application requiring electrical isolation. In conclusion, the OPIA801DTU is an optoisolator designed for application in various industrial, medical, and automotive systems. It is composed of an LED as the transmitter and a photosensor as the receiver, which is used to transfer signals between circuits with complete electrical insulation. It provides low signal propagation delay, high common mode rejection ratio, wide power supply voltage range, adjustable gain, and low EMI, making it a universal optoisolator for all types of applications.
