Isolated ESD Diode Grounding (TPD8E003DQDR)

Praveen N1
Intellectual 430 points

Hi,

In the design, we are using two sections. 

Isolated and Non-Isolated section. In the isolated section, we have given a connector and we provided ESD Diode (TPD8E003DQDR).

Now the issue is we connected this ESD diode ground in Isolated ground. when the ESD is passed to the Connector. The High surge will be affecting the isolated section because ESD is connected to isolated ground.

Here, How I need to connect the ESD ground in the Isolated section or how I need to reduce the high surge in the isolated section.

Thanks 

Praveen
