What is an electrostatic discharge protection diode?

Time：2025-12-18 Views：55次

Share：

An electrostatic discharge (ESD) protection diode is a zener diode optimized specifically for ESD protection applications. It serves to protect integrated circuits from damage caused by overvoltages, such as electrostatic discharge, which are higher than the rated withstand voltage of the integrated circuits and may enter the circuit board through external ports, such as USB ports.
