Tool/software:
Hello,
My customer has communication error issue at 6kV with TPD4E02B04 even though the datasheet says +/-12kV. Their previous board didn't have communication issue on gigabit ethernet even at 6kV and had the issue without ESD protection devices on their new board, so they thought ESD protection device would be required and put TPD4E02B04. The performance has improved a little, but they still had communication issue. Would you please tell me what they would need to do to work on gigabit ethernet? Do they need to use another protection device other than TPD4E02B04 like ESD401 since the datasheet on top page of TPD4E02B04 doesn't say ethernet for interfaces?
Note that they asked module to an external company, so they don't know which ESD protection device is used. The label on the device says "1436H", but it didn't hit as ESD protection device from the internet search. Note also that they need 4-ch.
Best Regards,
Yoshikazu Kawasaki
