Our IRF530NPBF transistor failed (electrical overload). After decapsulation, we found that its structure is not HEXFET (photo attached). Is this possible, or is it not the original transistor?

The part is a kind of generic, produced more than 25 years. So many companies produce parts with the similar name, like this https://www.alldatasheet.com/view.jsp?Searchword=IRF530 list. Even there are many non original products. To be sure that you buy original product, you must buy it from Infineon distributor.

We also found a marking on the die with the date 2000 year and the inscriptions IR Corp and FET (attached). I also attached a photo of the transistor. It looks like the transistor and die are original, but not HEXFET techolnology. Strange thing...
