The CNW83300 is an optoisolator with a transistor, photovoltaic output that features excellent isolation and long-term stability. Optoisolators are used to allow a signal on one side of an isolation barrier to act as a control signal while protecting the user from potentially hazardous or damaging voltages. The CNW83300 has various benefits when compared to traditional isolator methods, such as gate drive optocouplers and transformers, such as increased electrical isolation, better signal integrity, and improved immunity to EMI. This article will discuss the application field and working principle of the CNW83300.

The most common application field for CNW83300 optoisolators is in industrial automation applications, such as motor control, motion control, safety systems, and process control. The device is also used in more general safety-related applications, such as in medical equipment, street and traffic safety, and burglar alarms. The opto isolator is designed to provide complete electrical isolation of the input and output signals, which can protect both the control device and the equipment it is controlling. The CNW83300 can provide isolation up to 7000Vrms for up to 1 minute and can operate over a wide temperature range of -40°C to +100°C. The optoisolator also comes with several features that can help improve its performance, including low propagation delay, a wide LED dynamic range, noise immunity, and a low start-up current.

The CNW83300 optoisolator works by using a photovoltaic cell to convert light into electrical current. The device consists of a photo diode, a light emitting diode, two inverting transistors, and two output transistors. The light emitting diode acts as an input and the photodiode as an output. When the input is illuminated, the photodiode produces a current, which is then inverted by the transistors and output as an electrical signal. The output is then passed through the two output transistors, which invert it back to its original form. The CNW83300 is designed to provide extremely high electrical isolation, allowing signals to be transmitted without any conductive connection between the two sides.

The CNW83300 optoisolator is designed to be reliable in both harsh and benign environments, with features such as high common-mode transient immunity (CMTI) up to 200kV/µs, operational lifetimes of up to 100 million cycles, and an open collector output feature that allows it to be used as a DC contactor. The device also offers adjustable power-on electrical characteristics, allowing the user to select the best performance settings. The device is also designed with a low start-up current, which helps to reduce power consumption and improve reliability.

The CNW83300 opto isolator is a powerful tool for isolating electrical circuits, and its benefits extend beyond high isolation and long-term stability. The device is designed to offer a wide range of electrical voltage and current ratings, making it suitable for a host of industrial automation and general safety applications. The device also comes with features such as high common-mode transient immunity and adjustable power-on electrical characteristics, which make it a reliable and versatile tool for signal isolation.
