            Re: IC Marking Codes and Datasheets #2

            I need help identifying this IC, it's from an Intel NUC NUC6CAYB, attached are 2 photos of the IC and 1 photo of a normal motherboard found on the Internet.

            I think the marking reads RG5WK or R65WK and the other photo reads RG5VC or R65VC I think

              So I think I found it, but I'm not sure: https://www.ebay.com/itm/334488627756

              Is it SYX198CQNC ? What does this IC do? The NUC is flashing RAM problem.

                Appears to be a dual mosfet from Silergy. Replace it from a donor board or from AliExpress.

                US $4.59 15%OFF | 10pcs SYX198BQNC SYX198B SYX198 (RF4BJ RF3CG RF2BN RF...) QFN-6

                Do share the full markings with the vendor before purchasing.

                    What is logic board # of this Dell? LA-**** markings. This part is likely from Silergy.

                                  A diode marked as PJ8017, but I can't find it on Aliexpress.

                                  I need to find the correct part number.

                                    Re: IC Marking Codes and Datasheets #2

                                    I think I found it, using a similar schematic, it seems to be P4SMAFJ20A since they have IV as their marking.

                                    It seems to be a Transient Voltage Suppressor (TVS) diode, can I replace it with a Schottky Diode?

                                      Can you share more details on which board contains this diode ? PJ may be Panjit (Taiwan).

                                        It's the G7BF, there's no schematic for it, I think it's similar to DAG7BFMB8D0.
