what do you think of this one? more expensive than i was hoping for, but it DOES take the place of the power mosfets, power diodes, clamps, screws, thermal interface material, and soldering time. now the question is....how much overkill would it be to run four in parallel? since i'm planning to run 400 volts in and then only 200 volts out....the max current out should be twice the current in. we're getting up into the zilla 4k range if i run four of them in parallel.

what are your (anyone who reads this) thoughts?

What do you intend to drive with this?
If you are limiting the duty cycle to 50% - and I wonder why you would do that, how are you going to limit the current?
