ESD Protection

ESD Performance of the USB1T1103

HBM D/D: 15.0kV

HBM, all other terminals (Mil-Std 883E): 6.5kV

ESD Protection: D/D Terminals

Since the differential terminals of a USB transceiver may

be subjected to extreme ESD voltages, additional immunity

has been included in the D and D terminals without com-

promising performance. The USB1T1103 differential termi-

nals have ESD protection to the following limits:

• 15kV using the contact Human Body Model

• 8kV using the Contact Discharge method as specified in

IEC 61000-4-2

Human Body Model

Figure 1 shows the schematic representation of the Human

Body Model ESD event. Figure 2 is the ideal waveform rep-

resentation of the Human Body Model.

IEC 61000-4-2, IEC 60749-26 and IEC 60749-27

The IEC 61000-4-2 standard covers ESD testing and per-

formance of finished equipment, and as such evaluates the

equipment in its entirety for ESD immunity. Fairchild

Semiconductor has evaluated this device using the

IEC 6100-4-2 representative system model depicted in Fig-

ure 3. Under the additional standards set forth by the IEC,

this device is also compliant with IEC 60749-26 (HBM) and

IEC 60749-27 (MM).
