""I have carefully forgotten where I buy my MOSFETs :-)""Well, they say memory is the second thing to go...I forgot what the first thing was.
""My SAAB 9000 2.3 Turbo has now done 240.000 Miles and still it is so quiet, that one of my distributors fell asleep, while I drove us home from the Frankfurt show at 125 MPH. ""
The last time a distributer fell asleep in my car, it had to be towed.
Perhaps he didn't share your musical taste?:-)""Does SAAB Turbo motors last long? I don't know yet""
240,000 miles??? Yes, you do know they last long. Just not how long.
(My minivan can match your SAAB on a weight times distance basis.)
Last time I ran large die mosfets, was IXYS die "6". Tried running them "hot", 50-60 Khz switching. Found the biggest issue was passing through linear region. Subber design was very touchy, as it was a tradeoff between on and off, the polysilicon gate material introduced across the die prop. delays. But I'm still jealous!!!
That die size, you must be using BeO substrate with kovar (yuck) package, or maybe some clad copper for TCE match.
