Optoisolators are components that separate two electrically isolated devices or circuits. This type of electrical isolation is achieved through the use of a light-sensing device, such as a photodiode. Optoisolators are important for providing protection from line-to-line voltage spikes and surges, making them an essential component for power protection and distribution systems. They are particularly useful when communicating between two systems that use different reference potentials, allowing for the transmission of signals between the two systems without any electricity flow. An optoisolator such as the CNY173SR2M is especially beneficial for use in switching power supply circuits and protecting sensitive control or computer circuitry.

The CNY173SR2M optoisolator is a transistor, photovoltaic output device that includes both an infra-red transistor and an integrated photodiode. It is designed for use in low-production cost products, providing an affordable alternative to more expensive components without sacrificing reliability and performance. Its operating frequency range is from 10 kHz to 20 kHz, making it suitable for use in a variety of applications. It is also capable of handling voltage up to 600V, making it a very rugged component for use in harsh environments. In addition, the device is designed with low lead inductance and low substrate capacitance, making it ideal for high-speed switching applications.

The CNY173SR2M optoisolator works by using a light source, such as an infrared LED, to trigger a photodiode. The photodiode in turn switches a transistor on. When the transistor is switched on, an electrically isolating barrier is created between the input source (the infrared LED) and the output (the transistor). This isolation barrier prevents electrical interference and allows for transmitting signals between the two systems without current flow. This type of optoisolator is often used in applications such as overvoltage protection systems, motor controls, audio amplifiers, and industrial controls.

The CNY173SR2M optoisolator is a great option for use in high-speed applications because it has a very low lead inductance and low substrate capacitance, allowing for a high-frequency response. Furthermore, it is designed with a maximum operating voltage of 600V, making it extremely reliable even in harsh environments. This optoisolator is also designed with a wide operating temperature range, from -40°C to +85°C, giving it excellent temperature tolerance. The CNY173SR2M is a versatile optoisolator that is suitable for use in a wide variety of applications and environments.
