ESD Protection DevicesESD protection devices, or electrostatic discharge protection devices, are used to protect electronic circuits from damage due to electrostatic discharge (ESD). ESD can occur when two objects with different electrostatic potentials come into contact, causing a sudden flow of current between them. This can damage or destroy sensitive electronic components, such as integrated circuits, if they are not protected. ESD protection devices work by providing a low-resistance path for the ESD current to flow, which allows it to be safely dissipated without damaging the protected circuit. Examples of ESD protection devices include diodes, transistors, and other specialized ICs.
