5 Layout considerations for TVS diodes (ESD protection diodes)

Based on waffle layout style, two modified layout styles have been proposed, which are called as multi-waffle and multi-waffle-hollow layout styles.

A TVS is an array of diodes (see Figure 2 for a typical example) arranged to present a very high impedance to the voltages normally present in the circuit, but ...

As shown in the circuit diagram, the TVS diodes are placed between the connector exposed to the outside of the chassis and the IC so that the TVS diodes can ...

In this article, we'll show where to place a TVS diode in a PCB layout, particularly near connectors mounted along a board edge.

You will learn basic knowledge such as basic operation, principle, and basic circuit of TVS diode(ESD protection diodes). What is a TVS diode (ESD... · Key electrical characteristics of...

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 ...

Place diode close to the potential ESD entry points, such as connectors, buttons, or exposed pads, is essential. This ensures the static energy ...

The parasitic inductance LPARASITIC due to the layout is always present between the protection diode and the ground.

The first section helps define the key parameters for ESD devices. The second section offers tips for printed circuit board (PCB) layout designs.

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.
