10 Power Supply Recommendations

This device is a passive EMI and ESD device so there is no need to power it. Care should be taken to not violate

11 Layout

11.1 Layout Guidelines

•

The optimum placement is as close to the connector as possible.

–

EMI during an ESD event can couple from the trace being struck to other nearby unprotected traces,

resulting in early system failures.

–

The PCB designer needs to minimize the possibility of EMI coupling by keeping any unprotected traces

away from the protected traces which are between the TVS and the connector.

•

Route the protected traces as straight as possible.

•

Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded

corners with the largest radii possible.

–

Electric fields tend to build up on corners, increasing EMI coupling.

11.2 Layout Example

This application is typical of an 18-bit RGB display panel layout.
