Abstract

Electrostatic discharge (ESD) protection is essential on a system-level design for a wide range of end-equipment in consumer, industrial, and automotive spaces. One ESD strike to an unprotected system could cause permanent damage to the overall system. By splitting into three sections, this guide helps with selecting the proper transient voltage suppressor (TVS) for ESD protection in a system design. The first section helps define the key parameters for ESD devices. The second section offers tips for printed circuit board (PCB) layout designs. The last section provides TI ESD devices that are categorized by the package types, allowing a quick selection process for ESD devices based on the package and footprint.
