Re: Good IGBT List?

Another mistake experimenters make, in being economically frugal, it 
to buy their semiconductors off E-Bay or from a surplus house.  Many 
of these are factory "seconds" that do not meet the normal 
manufacturer's standards. Sometimes it's only cosmetic, but other 
times it has flaws which will cause electrical failure.

I've seen people degrade manufacturers for bad products when they 
have purchased "seconds" that failed.

Also, most Tesla experimenters are operating the IGBTs at or above 
their rated values.  This also can cause premature failure of the 
semiconductor.

If you are on a tight budget you must be willing to accept 
occassional failures.
