ESD122: Back drive protection

Mike Ulrich

Part Number: ESD122

I am looking for a device to provide USB2.0 protection, and powered by 3.3V. Does the ESD122 provide back drive protection? If not, can you recommend a device that does?

Thank You.

Hello,

You mean reverse current protection?

Yes. They are the same thing.

Hello,

This is just an ESD diode it does not have the capability of blocking current on the signal path. This only shunts current during a quick transient like ESD.

I would recommend looking at something like the TPD3S714 that is with a different team.
