Optoisolators - Transistor, Photovoltaic Output are widely used in high-frequency signal isolating applications due to its stable performance. CNY117F-3 is one of the popular optoisolators in the industry today. This article will elaborate on its application field and its working principle.

CNY117F-3 optoisolator is mainly applied in the digital signal free isolation and protecting circuits, such as power systems, motor drives, and industrial automation. The optoisolator is able to provide isolation between input and output signals, extend the range of isolation voltage, and reduce conduction path resistance. In the industrial field, CNY117F-3 optoisolator is used to enhance the immunity of some sensitive components, thus improving the stability of the system. Besides, CNY117F-3 opto-isolator can be also used as insulation amplifier in differential signal amplifier application.

The working principle of CNY117F-3 optoisolator is based on the photo-electric effect. It includes three parts: LED, photocoupler, and phototransistor. The LED is located at one side of the optoisolator and can emit light when electricity flows in; the photoresponsive components at the other side of optoisolator will change the resistance when illuminated; finally, the phototransistor is connected to the photoresponsive components, it amplifies the light current and empowers the output current.

CNY117F-3 optoisolator has numerous advantages compared to other optoisolators. It has a wide operating voltage range from 4V-30V and can be used in both AC and DC circuits. The fast responding speed of CNY117F-3 and its wide current range makes it particularly suitable for switching operations. Thanks to the advance technology of integrated planar chip, CNY117F-3 optoisolator has much higher reliability than ordinary fiber transmission. Also, it has a long life-expectancy of 5 million and integrates a heat conducting material for better heat dissipation.

In conclusion, CNY117F-3 optoisolator is an efficient and reliable isolation device widely used in industrial, motor drive, and digital signal free isolation applications. Its working principle lies in the photo-electric effect, it has great advantages which include wide operating voltage, fast response time, high reliability, and low heat dissipation. All in all, CNY117F-3 optoisolator is a great way to improve insulation performance in any intelligent apparatus.
