Hi all, I currently have a J-link Plus Compact kit, but now when I connect to the computer, the COM port is not displayed, I checked, the components were damaged near the connection port like the red circle in the picture. Does anyone know what it is an IC with P/N? Please let me know to replace it

Hi,
Before replacing anything, did you make sure that VCOM was not disabled for the J-Link Compact?

FabianHi Fabian,
Thank you for your information.I have checked very carefully it did not receive COM port, besides that IC was burned, and completely damaged, please tell me its P/N?

Hi,
sorry for the delay in response.
Even though it is probably not required anymore, please find the answer below:In general we recommend to make use of our trade-in program in such a case:
https://www.segger.com/purchase/trade-in-program/The damaged part is an ESD-Protection.
You could try to unsolder the part and check if the OB still works, as it also works without the part.
If so, you can replace the part with a new IC (On Semi NUP4114UCW1T2G).
If it does not, more parts were damaged by the over current and the whole J-Link is unusable.BR
