Optoisolators are electronic devices which are used for isolating two circuits electrically, while permitting them to communicate through light. The HCNR201#350 is a four-pin, single-channel, photovoltaic output optoisolator with an internal LED. It is an integrated optical interface that provides a high level of electrical isolation between two independent circuits. It features a fast response time, low current drain, and an extended operating temperature range, making it an attractive choice for a variety of applications.

The HCNR201#350 optoisolator is typically used in applications where there is a need for electrical isolation between two independent circuits. It allows two circuits to communicate with each other without a direct electrical connection. This makes it ideal for applications such as isolating power supplies, protecting sensitive circuitry, and connecting between different signal levels or isolated ground systems. It is commonly used in industrial, medical, and automotive applications.

The operating principle of the HCNR201#350 optoisolator is based on an LED embedded within the package. When an input voltage is applied between the pins, the LED emits light which is then detected by a photosensitive detector. This output voltage is then isolated from the input and can be used to drive other circuits. This device features a typical current transfer ratio of 500%, which means it can provide up to 500mA of current for every 1mA of input current.

In addition to providing electrical isolation, the HCNR201#350 optoisolator also offers noise immunity. It has a high common mode transient immunity (CMR) that helps protect against large voltage surges and transients. This device also features integrated EMC/EMI filters that provide high levels of protection against electromagnetic interference and electrostatic discharge (ESD). This makes it well suited for use in applications where noise immunity is required.

The HCNR201#350 optoisolator is available in a 4-pin single-channel configuration. It is available in a wide variety of packages, including DIP, SMD, and surface-mount varieties. The device has a wide operating temperature range of -40°C to +110°C, making it suitable for a variety of applications in extreme environments.

The HCNR201#350 optoisolator is typically used in a variety of applications including industrial automation, medical devices, automotive electronics, communications and telecoms, and white goods. In medical applications, it can be used to protect sensitive circuits from interference from other electrical sources. In automotive applications, it is commonly used for communication between the engine control unit and the instrument panel and for connecting different signal levels. In industrial automation and white goods, it is often used to protect against interference from other electronic equipment.

The HCNR201#350 optoisolator offers a high level of electrical isolation which makes it an ideal choice for use in a wide range of applications. Its fast response time and low current draw make it an attractive choice for applications where noise immunity, speed and accuracy are important. It is also well suited for use in extreme environments due to its extended temperature range.
