Looking for a fet

Has anybody got a clue on how I might get or even perform a search for a high voltage power fet (>250v), preferably n-channel, that
doesn't have an internal zener? It must also have a low on-resistance.
I'm attempting to change the damping of a large back emf on the fly and the internal zener turns on defeating the exercise in
anyconfiguration I can imagine. The fet will be protected by other means from over voltage so this isn't an issue. Early line output
transistors needed an external diode, does anyone know of a fet that was produced without one built in? This has had me stumped for
years and I would like to sort it out. Patents also show a fet being used in this configuration so they must exist somewhere.
Rob.
