Dear experts,

We bought IRLML9301MTRPBF from franchised source.
During inspection, we observed nn the same date code:
1. Different die sizes
2. Different number of wires
3. Different country of diffusion. China n Philippines.

I cannot find any PCN on this on Infineon nor any public domain.
Can you advise if both are LOT are valid n share a copy of the PCN if it's available. Thank you!

Hi Shawnfong,

After checking with the packaging team regarding this issue, we have got the following response,
the parts which you have received are counterfeit. Please take up this issue with the distributor. The chip is not even ours inside the package. The bad batch will have to be replaced and a counterfeit investigation has been initiated with the distributor. The real geometry is as shown below,
