8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TPD2E2U06-Q1 device is a diode type TVS which is typically used to provide a path to ground for

dissipating ESD events on hi-speed signal lines between a human interface connector and a system. As the

current from ESD passes through the TVS, only a small voltage drop is present across the diode. This is the

level for the protected IC.
