speaking of higher power versions:

freewheel diodes:
Digi-Key - APT100S20BGMI-ND (Manufacturer - APT100S20BG)

Mosfets:

There are also higher voltage mosfets in that same family with only slightly higher rdsOn, so a 200-250v mosfet based controller isn't that unthinkable. There are lots of diodes with really high voltage ratings.
