The CNX35UW optoisolator is designed for a wide variety of applications in industrial, automotive, and medical systems. It provides galvanic isolation from the input to the output and is designed for use in high temperature environments. The optoisolator’s input circuit is suitable for a variety of conduction-mode inputs, such as noisy contact closures, digital tachometers, and PCBs with digital-controlled switches. The output circuit is built with a transistor with photovoltaic-output, which allows the user to interface easily with low-power digital integrated circuits and PLCs. The optoisolator also features an isolation voltage of 3750Vrms and isolation current of c + 5 milliampere, which makes it suitable for applications that require galvanic isolation.

The working principle of the CNX35UW is relatively simple. When the optoisolator is powered on, its photovoltaic output transistor is in an off state. When an input signal is detected, the input current passes through the optoisolator, which triggers the photovoltaic output transistor to turn on. This causes a voltage potential across the collector-emitter terminals of the transistor, thus providing an output signal that can be monitored and used as a control signal. The output signal is then isolated from the input signal, which prevents any interference or electrical noise from affecting the output signal.

The CNX35UW is suitable for applications where isolation between the input and output signals is required, such as in industrial automation and automotive control systems. Its strong isolation voltage and current capabilities make it an ideal choice for applications that require galvanic isolation between high-voltage and sensitive components. The optoisolator’s small size and low power requirements also make it an ideal choice for portable/mobile applications.

In summary, the CNX35UW optoisolator is an ideal choice for a wide range of applications in industrial, automotive, and medical systems. The optoisolator’s input circuit is suitable for a variety of conduction-mode inputs, while its output circuit is built with a transistor with photovoltaic-output. The optoisolator also features an isolation voltage of 3750Vrms, as well as an isolation current of c + 5 milliampere, which makes it suitable for applications that require galvanic isolation. The optoisolator’s small size and low power requirements also make it an ideal choice for portable/mobile applications.
