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. Customers should validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TPD4E02B04-Q1 is a diode type TVS which is used to provide a path to ground for dissipating ESD events on high-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 the protected IC. The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a safe level for the protected IC.

8.2 Typical Application

8.2.1 Design Requirements

For this design example two TPD4E02B04-Q1 devices and two TPD4E05U06 devices are being used in a USB 3.1 Gen 2 Type-C application. This provides a complete ESD protection scheme.

Given the USB 3.1 Gen 2 Type-C application, the parameters listed in Table 1 are known.

Table 1. Design Parameters

DESIGN PARAMETER VALUE
Signal Range on SuperSpeed+ Lines 0 V to 3.6 V
Operating Frequency on SuperSpeed+ Lines 5 GHz
Signal Range on CC, SBU, and DP/DM Lines 0 V to 5 V
Operating Frequency on CC, SBU, and DP/DM Lines up to 480 MHz

8.2.2 Detailed Design Procedure

8.2.2.1 Signal Range

The TPD4E02B04-Q1 supports signal ranges between –3.6 V and 3.6 V, which supports the SuperSpeed+ pairs on the USB Type-C application. The TPD4E05U06 supports signal ranges between 0 V and 5.5 V, which supports the CC, SBU, and DP/DM lines.

8.2.2.2 Operating Frequency

The TPD4E02B04-Q1 has a 0.25 pF (typical) capacitance, which supports the USB3.1 Gen 2 data rates of 10 Gbps. The TPD4E05U06 has a 0.5 pF (typical) capacitance, which easily supports the CC, SBU, and DP/DM data rates.
