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
