Best practice for placing ESD protection devices on a PCB

ABSTRACT. Successfully protecting a system against electrostatic discharge (ESD) is largely dependent on the printed circuit board (PCB) design.

ESD protection parts such as Chip Varistors and Zener Diodes can efficiently protect against ESD when placed close to the ESD intrusion point.

Here are some ESD protection circuit design options you can use in your next PCB and some PCB layout best practices for your new product.

ESD protection design guidelines aim to prevent ESD events in terms of voltage as well as current.

1. Place ESD protection diodes close to the ESD entry point. 2. Minimize trace inductance in series with ESD protection diodes including GND after the board ...

ESD hardening of a system involves the electric, mechanical, and software design of a system. All exposed metal must be grounded to chassis ground. Hardening a ...

An ESD protection circuit prevents high-voltage spikes from damaging sensitive components like microprocessors, memory chips, and analog ICs.

If the path to be protected is on the same layer that the ESD source the best way is to route as in Figure 13. The parasitic inductance LTVS ...

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 ...

ESD selection guides are available in Technical Documents at www.ti.com/esd for guidance in choosing the correct type of TVS diode for a particular system. With ...
