LF: Protected FETs?

[G0MRF@aol.com]

Hello group.

Does anyone have any practical experience with any of the FETS that feature 
internal protection circuits?  PROFET SmartFET OmniFET etc
I'm investigating supply current limiting and was considering using one of 
these devices in series with the supply. It would have the advantage of 
protecting a power amp in the event of a PA FET failure, something which 
can't be achieved by simply removing the drive.
Just thought I would ask before spending money on expensive fuses!
