8.1.1 ESD Protection

It may be necessary to incorporate an ESD component to protect the TDP142-Q1 from electrostatic discharge (ESD). TI recommends following the ESD protection recommendations listed in Table 8-1. A clamp voltage greater than value specified in Table 8-1 may require a RESD on each differential pin. Place the ESD component near the USB connector.

Table 8-1 ESD Diodes Recommended Characteristics
ParameterRecommendation
Breakdown voltage≥ 3.5V for DP input pins
≥ 1.5V for non-DP input pins
I/O line capacitanceData rates ≤ 5Gbps: ≤ 0.50pF
Data rates > 5Gbps: ≤ 0.35pF
Delta capacitance between any P and N I/O pins≤ 0.07pF
Clamping voltage at 8A IPP IO to GND(1)≤ 4.5V
Typical dynamic resistance≤ 30mΩ
(1) According to IEC 61000-4-5 (8/20μs current waveform)
