Request ESD Suppressor for Gigabit Ethernet & USB2.0.

Hello Inho,

For USB 2.0, I would recommend ESD122 for he data line and TVS0500 for the VBUS line. 

For gigabit Ethernet, I would recommend TPD4E1U06.

Please let me know if you have anymore questions.

Regards,

Matt Smith 

Dear Matt,

I want to one part apply compatible for USB 2.0 & gigabit Ethernet.

Please, Recommand that part.

Thank you.

Best regards,

Hello Inho,

TPD4E1U06 should work for both USB 2.0 and gigabit Ethernet.

Matt Smith

Dear Matt,

Is that part compatible for RS-485/422 and RS-232?

Thank you.

Best Regards,

Inho Jeon.

Hello Inho,

Unfortunately not. RS-485 operating voltage levels go up to 12 V and TPD4E1U06 only has a Vrwm of 5.5 V. I would recommend TPD2E007 for RS-485/422 and RS-232 protection.

Dear Matt,

Thank you for reply.

Is "TPD4E001DRLR" possible for Gigabit Ethernet ESD suppressor? 

Thank you.

Hi Inho,

For gigabit Ethernet, probably not. It has a 1.5 pF line capacitance and will most likely compromise your signal integrity at 1 Gbps speeds.

Dear Matt,

You mean CI/O Channel input capacitance of TPD4E001DRLR is 1.5pF, Right?

And, ΔCIO-TO-GND  Variation of channel input capacitance of  TPD4E1U06  is 0.025p. That is right for SI at 1Gbps speeds Ethernet, Right?

Thank you.

Hi Inho,

Yes that is correct.
