Optoisolators are a type of electrical component that offers an electrical isolation functionality. The CNY 171M is a transistor photovoltaic output optoisolator that utilizes the isolation of light in order to provide an electrical isolation function. It is a popular choice for applications such as power controllers, interface isolation, signal conditioning, systems troubleshooting, and other industrial applications.

One of the most important features of this optoisolator is its ability to provide a high level of circuit isolation. It can handle up to 25V of input voltage, and its isolation barrier can withstand up to 1350Vrms, making it ideal for electrical applications that require a high level of isolation. Furthermore, the CNY 171M has a low on-resistance of 0.07Ω, making it suitable for applications with low power consumption and minimal voltage drop.

The CNY 171M’s construction is what makes it so effective. The optoisolator consists of a Light-Emitting Diode (LED) and an integrated phototransistor, which is then connected to an isolator. The LED and phototransistor pair, which is also known as the logic channel, is responsible for providing electrical isolation capabilities. When a current flows through the LED, it produces light, which is then picked up by the integrated phototransistor. The output signal from the phototransistor is then isolated from the input signal by the isolator.

The CNY 171M is designed to provide a maximum power rating of 10mW. It can be used in a variety of applications, such as: power controllers, noise-immune interfaces, signal conditioning devices, or other circuit protection devices. Additionally, the CNY 171M’s phototransistor is capable of a relatively large forward current, making it suitable for applications that require high gain. For added circuit protection, the phototransistor has an integrated h FE clamping circuit.

The CNY 171M is designed to offer a high level of electrical isolation, which is its primary purpose. Furthermore, its construction makes it well-suited for applications that require a high current capacity and low power consumption. The CNY 171M is an ideal optoisolator for power controllers, interface isolation, and even signal conditioning devices.
