Summary

RS-232 interface is the earliest serial interface standard, and has been widely used in short-distance (<15M) and low-baud-rate serial communications in industrial equipment, communication equipment and other fields. In complex electromagnetic environments, it is often threatened by electrical overstress (EOS) such as electrostatic discharge (ESD) and surge. Therefore, designing an effective RS-232 interface electrostatic and surge protection solution is crucial to the stability and reliability of the equipment.
