8 Application and Implementation

8.1 Application Information

The TPD4E05U06-Q1 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 voltage presented to

IC.

8.2 Typical Application

8.2.1 Design Requirements

For this design example, two TPD4E05U06-Q1 devices, and a TPD5S116 are being used in an HDMI 1.4

application. This provides a complete port protection scheme.

Given the HDMI 1.4 application, the parameters in Table 1 are known.

8.2.2 Detailed Design Procedure

To begin the design process, some parameters must be decided upon; the designer needs to know the following:

•

Signal range on all the protected lines

•

Operating frequency
