7.2.3 ESD Protection

It may be necessary to incorporate an ESD component to protect the TUSB1002A from electrostatic discharge (ESD). TI recommends following the ESD protection recommendations listed in Table 7-2. A clamp voltage greater than value specified in Table 7-2 may require a RESD on each differential pin. Place the ESD component near the USB connector.

Table 7-2 ESD Diodes Recommended Characteristics
Parameter Recommendation
Breakdown voltage ≥ 3.5V
I/O line capacitance Data 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)
