Optoisolators are electrical systems that use light and beam separation technology to provide electrical isolation between two parts of an electric circuit. They provide high isolation between the input and output and are widely used in areas such as motor control, which is especially susceptible to EMI or electromagnetic interference. The CNY173SVM optoisolator is based on the SiON technology of transistors, photovoltaic output, and exhibits excellent isolation, surge protection, and flame retardant properties. In this article, we will discuss the application fields and working principles of the CNY173SVM.

The CNY173SVM follows a two-pin industrial standard pins package for easy mounting. It has a minimum isolation voltage of 3500Vrms and a maximum current transfer ratio of 100%. The CNY173SVM can also work in an extreme temperature range from -40 to +125°C, making it suitable for a wide variety of applications. The optoisolator is integrated with a high-performance optical source and photovoltaic output circuits, as well as an advisory LED safety device. This feature ensures that the device maintains its highly reliable isolation performance throughout its service life.

The applications of the CNY173SVM are mainly found in motor control systems, including devices such as AC and DC motor controllers, servo-motor controllers, and speed controls. It can also be used in power supplies, amplifiers, scientific instruments, and other similar devices. In medical equipment applications, the CNY173SVM can help to ensure electromagnetic compatibility (EMC). It can also be used in security systems, preventing illegal access to sensitive data or control systems.

The working principle of the CNY173SVM is quite simple. It uses a balanced current transfer ratio across two pins, a collector and an emitter. The optical source transmits a beam of light into the photodiode which produces a current based on the intensity of the light. The output current is amplified by the transistor, and then sent to the collector pin of the optoisolator. This optoisolator also has a high isolation voltage of 3500Vrms, which ensures that the device is safe and reliable even when exposed to high voltage conditions.

The CNY173SVM is an efficient and reliable optoisolator that offers excellent isolation, surge protection, and flame retardant properties. It can be used in a variety of applications because of its industrial standard pins package and its ability to work in extreme temperatures. It also has a high isolation voltage of 3500Vrms, which makes the device safe and reliable. The optoisolator operates using a simple balanced current transfer ratio, ensuring that the current produced by the optical source is transferred to the collector pin.
