[Boatanchors] Two 400 Volt MOSFETs Equal...

[Ian Wilson]

The voltages across the two series devices will split according to the
ratio of the leakage currents through each device. So if the devices
are well-matched* then you can double the standoff voltage of a single
device. Prudence would suggest a 50% derating, so you could stand
off 600V with two 400V devices in series.

* well-matched = not an eBay "matched pair" :)
