Can the part marking be J3 instead of J8?  
The datasheet calls-out for a tolerance under the “Marking of 5%”

Hello,

The data sheet says J8 for that part number. I see the B version with part number MMSZ5248B was marked with the J3 suffix. [MMSZ5248B onsemi | Discrete Semiconductor Products | DigiKey](https://www.digikey.com/en/products/detail/onsemi/MMSZ5248B/1048674)

You can see the data sheet and it does list the J3 for the part mark. The reason I gave the product page liks this , is beacuse we do list some substitutes listed as direct. You were close, but this one appears to be what you have.

Got it, thanks.  
I do see the part properties between revisions are similar.
