Optoisolators are devices used in electrical engineering applications, which employ light-sensitive elements, along with circuitry, to provide electrical insulation between two systems. CNY66 optoisolators belong to the transistor-photovoltaic output (TPO) class of optoisolators.

The purpose of CNY66 optoisolators is to protect systems which are connected from each other from any electrical damages or noises. This aim can be achieved by providing isolation between the two systems. Separating the systems from each other eliminates any chances of transmitting electrical disturbances, allowing both to function without interference from one another.

The CNY66 optoisolator employs a photo transistor which is located within the package, and a light-emitting diode, or LED, which is also a part of the package. Connected to the LED is a diode which would protect the LED from any reverse voltages. This is known as the transient protection diode.

The CNY66 optoisolator works internally by the working of the two main components which are the LED on one side and the photo transistor on the other. First, the LED emits light when an electrical current is provided from the external circuit, which depends on the current requirements and the type of application. The light is then received by the phototransistor, which is connected to the power source via an external resistor, therefore allowing it to be turned on or off. When the light is received, it causes the phototransistor to be turned on; pushing the current from the power source into the protected circuit. When the LED is turned off, the phototransistor is also turned off, cutting the flow of current into the protected circuit. In this way, an isolated protection system is created for two systems that interact with each other.

The CNY66 optoisolator is capable of providing very high levels of isolation from the external environment, with values reaching as high as 14,000 Vrms. The operating frequencies can be as low as 1Hz - 750kHz, making them suitable for a wide variety of applications. The optoisolator is also extremely reliable and can be used in long-term and high-temperature operation. This makes the CNY66 optoisolator a very attractive option for industrial and commercial applications.

In conclusion, the CNY66 optoisolator makes for an effective and reliable way to isolate two systems which interact with each other. The optoisolator ensures that no electrical interference occurs and prevents any damage to equipment from surges and spikes in voltages. With its high levels of Isolation and wide operating frequencies, the CNY66 optoisolator is highly efficient and cost-effective to use in a wide range of applications.
