overvoltage protection using IGBTs

Hello

i want to make an overvoltage protection circuit for the 230V mains
but instead of varistors...or a circuit with thyristors...
i would like to try IGBTs if it is possible! i got one 600V/20A N-channel
but i don't know what to do since i got no idea how to use an igbt

can somebody help?

IGBTs are designed for fast high voltage switching, not this kind of thing.

Stick with varistors for this kind of application.

well...i thought i could use it for such purpose
but i guess not right?
