USB 3.0

Circuit Protection of USB 3.0



Design Notes:

Protection Application:
Solution Description:
As shown at the left, there are two options for protection. In the upper schematic, an SP3010 is used on the Super Speed lines, and an SP3003-02XTG is used on the High Speed lines. For an integrated approach, the SP3011-06UTG is used to protect all of the data lines (as shown below).
Companion Solutions:
Other solutions within the Littelfuse portfolio exist in addition to these recommendations. For example, if the operating current on the power bus is higher or lower, an appropriately rated PTC can be chosen.
Regulatory Issues:
The IEC 61000-4-2 will be the most appropriate standard that applies for this port. It supplies a test method for verifying that the end product is not susceptible to ESD events.
Unique Features:
Does not apply.
Application Warnings:
Does not apply.
