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, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The ESD752 and ESD7x2 are dual channel TVS diodes which are used to provide a path to ground for

dissipating ESD events on USB-PD or industrial IO signal lines. As the current from the ESD passes through the

TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC.
