"What is the max operating voltage for DN2540N5 "

400V

"Is it safe to use it as plate load on 750v B+ ?"

What do you think?

Use the 900V IXYS parts.

    I don't see any sensible way to assure that the voltage divides equally across each device.
    
    I would order the correct part.
    
    IXYS make depletion mode parts up to 1KV and 400W.
