    Hi @USING.1​ ,

    there should be a indeed a marking on the top surface of the device package, like the one here below:

    0693W000007ZJFDQA4.jpgCan you please send a picture of your device? Maybe it was discolored after soldering or application of a chemical coating...

    Thanks for reply. But this is not mentioned anywhere in datasheet. Please clarify ?

    Hi @USING.1​ ,

    no, it is not specified in the datasheet...

    This because the datasheet is generic, while the 2D matrix is related to the specific assy lot for the case tracking (it contains the product code, the week/year (usually in the format Y/WW) of assy etc...).
