 My continually-updated MOSFET spreadsheet (a portion
 of which appears in a few places in AoE III) now has
 over 1300 items, 380 in the 500 to 650-volt range.
 180 of these have lower Rds(on) than the IPD60R400CE.
 So it's entire a matter of choosing your tradeoffs.
 
 There are a many reasons against selecting a lower
 Rds(on): high capacitance, poor distributor stock,
 high cost, larger package, no SMT package avail...
