TPD4E02B04: Is it possible to support USB3.2/10Gbps

Hi Noriyuki,

Both have very similar electrical specs. While, TPD1E01B04 has slightly lower capacitance and slightly higher IEC rating, both will work well with a USB3.2/10Gbps interface. It honestly comes down to channel count for these two devices. TPD1E01B04 is single channel and TPD4E02B04 is 4 channel. Since USB 3.2 has 6 high speed data pins that need protection, you could use a combination of 1 TPD4E02B04 device and 2 TPD1E01B04 devices. We also have a 2 channel device, ESD122, that could replace the 2 TPD1E01B04 devices (page 15 of this guide: https://www.ti.com/lit/sg/sszb130c/sszb130c.pdf?ts=1630594207575&ref_url=https%253A%252F%252Fwww.ti.com%252Finterface%252Fcircuit-protection%252Fesd-surge-protection-ics%252Foverview.html). 

Let me know if you have any more questions.

Noriyuki,

Just because it is not explicitly stated to be recommended on that table does not mean that you shouldn't use it. It will still work well with USB 3.1 Gen 2 and can support 10 Gbps speeds. You can see on the first page of the datasheet that it is being used in a USB application. The reason ESD122 is the best is because it is a very small package with lower capacitance and higher IEC 61000-4-2 rating. Layout also might be a little easier with a 2 channel part as well.
