CSD19536KCS - Ability to hold that high amperage?

Other Parts Discussed in Thread: CSD19536KCS

The TI FET part number CSD19536KCS says it can process 150A, how is this possible? When 0 gauge wire is usually required to withstand such high amperage, how is it that those tiny pins do? Is it the type of metal? Also, do we need some sort of excess electron drain part to go with it? If so, could you provide the circuit layout? Also, is there some sort of need to guard against excess heat?

Dean,
I wrote a bit about this in my blog on FET's continuous current readings, found here: e2e.ti.com/.../understanding-mosfet-data-sheets-part-3

Basically, the 150A is a function of the package and the number and thickness of the bond wires inside connecting the die to the source pin.

Whether the device can handle that much current thermally before overheating is an entirely different story. That depends on the board conditions, and the case to ambient thermal resistance.
