STF202 ? 22T1G
The Figure 10 describes in a simplified way what the USB
port components are. As shown in this diagram, there are
signals for upstream and downstream ports which must be
provided with Line Termination and EMI Filtering to meet
the requirements of the USB specification revision 1.1. In
addition to the Line termination and EMI Filtering, it is also
needed to protect the USB I/O Lines against ESD
conditions, so TVS devices must be added for these
purposes.

As mentioned before, the ON Semiconductor STF202
device provides “upstream termination”, EMI Filtering and
ESD Protection to IEC61000 ? 4 ? 2 in an integrated solution
placed in a small and single package (TSOP ? 6, Case 318G).
The typical application for the STF202 device is shown in
the Figure 11.
