ESD protection

Reference video 1. ESD/Surge Protection Basics ESD explanation Electrostatic Discharge, a sudden release of elctricity from one charge object to another, when objects come into contact ICs typicallly very sensitive to ESD, often interfaced to ‘outside world’ via connectors. often use TVS diode or ESD diode to avoid this issue. 2. TVS Diode Operation TVS Diode Operation 3. TVS Diode parameters 1. Uni- or Bi-directional Uni-directional: Asymmetric I-V curve Protect signal lines that are always above/below reference Bi-directional: Symmetric I-V curve Protect signal lines that can swing above/below reference 2.
