Default Intel Pro/1000 PT BLK TVS diode

A few months ago I received a network card that no longer connected to the network, although it was seen in the device manager and the drivers were installed automatically. Intel Proset Software also diagnose a TX signal problem.
At first glance, I thought it was a driver problem and I installed a clean Windows, but the problems persisted. Last week I came to the place where I have most of my tools and I decided to inspect it very carefully with a magnifying glass.
Only reflection of natural light helped me to find a piece of 2,5x2,5mm with a slightly burned look, a sign that made me think there was a short-circuit there. This is a 3304N

The protective features offered by this diode make me think that there was a serious problem because when I tried to desolder, it just disintegrated and took with it the pad that I suspect as holding a ground role and 4 pins. Of the 10 pins I noticed that only 4 connects, as the routes suggest.
Is there a risk that the Pulse h5078nl will also be affected?

I thought I'd give him another chance, but I need some help with diode grounding and the connections of the four pins.
