Optoisolators are a helpful tool that use a light source – typically an LED – to transfer current between two systems. The CNY17-4S (TA)-V is a type of optoisolator that is especially useful in a variety of different applications, due to its transistor and photovoltaic output. It is especially beneficial in situations where it is essential for a system to remain isolated from high voltages, or where a sensitive device is being used.

The CNY17-4S (TA)-V offers superior insulation between input and output of the optoisolator, with a breakdown voltage of at least 6000 V rms. It has a CTR value for the detection of current that is typically greater than 30mW/mA. Additionally, the CNY17-4S (TA)-V has an isolation voltage of 5000V rms, and a LED forward current of 1mA—making it a higher-performing device.

The CNY17-4S (TA)-V provides an indispensable number of features: for example, it has an extremely low ION saturation current, as well as a high I/O isolation. It also has wide operating temperature ranges from -40 to +85 °C, allowing for its use in a variety of settings. Additionally, the CNY17-4S (TA)-V has a small size compared to other optoisolators, making it easier to install in tight quarters.

The CNY17-4S (TA)-V is most often used in applications related to automotive instrumentation and automotive safety systems, such as airbag controllers. It can also be used in controlling systems for medical diagnostic equipment, in alarm systems, or in ticket machines. It is well-suited to these systems due to its small size, high-isolation, and I/O saturation.

The working principle behind the CNY17-4S (TA)-V is relatively simple. When the input voltage is applied to the LED, it emits a light which is detected by the photodetector. This photodetector then amplifies the signal and is then transferred to the output, creating a non-contact transfer of current. This process ensures that the signal that is being delivered is not exposed to any type of interference, making it a highly reliable option for any application.

The CNY17-4S (TA)-V optoisolator is a convenient and reliable device that has become a necessity for many applications. Its small size and high-performance make it an ideal choice for automotive uses and medical diagnostic equipment, or in any situation that needs reliable isolation. Additionally, its working principle is simple to understand, making it easy to implement and use in any system.
