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! 73 David G0MRF
