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 ESD751 and ESD761 are single channel TVS diodes which are used to provide a path to ground for

dissipating ESD events on USB-PD or industrial I/O lines. As the current from ESD passes through the TVS,

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

RDYN of the triggered TVS holds this voltage, VCLAMP, to a safe level for the protected IC.
