Optoisolators—Transistor, Photovoltaic Output are widely used in today’s electrical applications to provide electrical isolation between two separate circuits. One of the most popular models is the CQY80N. This optoisolator is known for its high level of performance and reliability, making it a trusted component by professional engineers and amateurs alike. In this article, we will explore the CQY80N’s application field and working principle.

Application Field

The CQY80N is a versatile optoisolator that can be used in a broad range of applications. It is especially useful when it comes to protecting sensitive circuits from interference from outside sources. The CQY80N is designed to block the flow of both electrical current and voltage, which makes it ideal for providing electrical isolation between different components or circuits. This optoisolator is often used in industries such as medical equipment, industrial automation, high voltage equipment, and security systems.

The CQY80N is also an excellent choice for power supplies, inverters, and other voltage conversion applications. It is highly reliable and has been designed to meet strict safety standards, making it an ideal choice for these applications. The CQY80N is also known for its superior immunity to electromagnetic interference, making it suitable for use in environments where there is high levels of electromagnetic interference.

Working Principle

The CQY80N is based on the principle of optoisolation. It uses an illuminated LED (Light Emitting Diode) to provide isolation between low-voltage and high-voltage sources. The low voltage side is connected to the LED, while the high voltage side is connected to a transistor or photodiode. When the LED is illuminated, it emits a small amount of light which is used to trigger the transistor or photodiode. This triggers the current on the high voltage side, allowing current to flow through the optoisolator.

The CQY80N also has a unique design that protects against overvoltage and short circuit conditions. It is also equipped with a second transistor layer which provides extra protection against overcurrents. This device also offers excellent temperature stability to ensure reliable operation over a wide range of temperatures.

The CQY80N is an excellent choice for many voltage and current-sensing applications, as it provides superior performance and reliability. Its optoisolation technology allows easy integration with other components and circuits, making it an ideal choice for both professionals and hobbyists. Its robust construction and superior performance make it a trusted component in many industries.
