hi IFX Team, I notice that the package of BSZ009NE2LS5 is described as “PQFN3.3*3.3 Fused lead”. I compare the dimention of this package with the standard PQFN3.3*3.3 package but no obvious difference is found. Does it mean the so-called "Fused lead" is more easy to be burned to open-circuit status when the device failed? Thanks!

No, fused lead means the source pads are combined into one.

Hi cafetea,
Thanks for your patience. I have confirmed the package PQFN3.3*3.3 fused lead and PQFN3.3*3.3 standard again and find out they have different package.
This is the PQFN3.3*3.3 fused lead as you said:
And this following is PQFN3.3*3.3 standard package:
Moreover, PQFN3.3*3.3 standard has also some other old versions.
Thanks,
Xiangrui

Hi Xiangrui, thanks for your reply! I am curious that why the non-standard PQFN 3.3*3.3 package is called "fused lead". Is there any different behavior of the package when the device is endured overpower or overcurrent stress?
