Re: [PSES] ESD protection for USB 3.0

[Brian Oconnell]

Just finished with a box having USB port - what a pain.  Test, testing, and yet 
more tests are the only way to go.

Lotsa stuff and papers from TI, On semi, TE, Littelfuse, etc. If you are very 
lucky, and the space aliens do interfere, you may be able to find a FAE that 
actually knows this stuff and can save you from making poor layout and 
component selection decisions. That is, the physical construction of your box 
can be just as important as the TVS that is incorporated. Lotsa luck.

Hello all,

Does anyone have a paper/info on the problems of (and hopefully the solutions 
for!) ESD protection 
on the USB3.0 interface?

It's generally best to install transient protection on the data lines. Several 
companies make devices for USB 3.0. I have some info here:
