Optoisolators - Transistor, Photovoltaic Output, are a type of optical isolator based on transistor switches and photovoltaic output. The CNX35U300 is a member of this family; its applications and working principles are discussed below.

The CNX35U300 is a photovoltaic optoisolator with a 2-pin header. This device offers a wide array of features including: a high operating voltage up to 24 VDC; low on-state resistance of 2.5 kΩ; low switching voltage of 0.5 V; and a fast response time of 0.5 ms. These features make it ideal for applications such as: isolated power supplies, automation control, digital logic circuits, and digital switching circuits.

The main purpose of using the CNX35U300 is to provide electrical isolation between the two circuits. This isolation is achieved by using a photo-current generated by a photo-diode to turn an NPN transistor on and off. When the photo-diode is activated, the transistor is switched on; when it is deactivated, the transistor is switched off. This way, the two circuits are electrically insulated from each other, while low current signals are able to travel between them.

In addition to its isolation capabilities, the CNX35U300 offers several other advantages. First, it can switch signals with a response time of 0.5 ms, even for short pulses. This makes it ideal for applications that require quick response times such as automation control. Second, it has a low on-state resistance of 2.5 kΩ, allowing for a high current load. Third, it can operate up to 24 VDC, allowing for higher voltage operations as well. Fourth, it has low diode forward voltage, reducing the amount of power loss during operation.

The CNX35U300 is a highly reliable device with a long life expectancy and a high level of accuracy. It also features a wide input voltage range from 5 to 24 VDC, making it suitable for a variety of applications. Furthermore, it requires no trimming or adjustment, allowing for quick and easy installation and maintenance.

In conclusion, the CNX35U300 is a versatile and reliable optoisolator. Its wide range of features make it a great choice for applications that require isolation, response time, and low power loss. Its low cost, high accuracy, and long life expectancy make it an ideal choice for isolating two circuits with different protocols.
