Hi Sir.

CSD17573Q5B can replace competitor MOSFET CED93A3 ( TO-252 ) ?

Can suggest how to PCB layout for CSD17573Q5B, if we need Id current 100A ?

Kuo,
In general, QFN's can replace DPAK devices no problem.

However, do you really need to push 100A through this device in actual application? In general, we would not recommend dissipating more than 3W or so in either of these packages.

Here is a blog I wrote one currents a while back that should clear some of this up:
