@s34g2000cwa.googlegroups.com:

Where could
I start looking for a supplier of this device. I only
want a one off.

Type W20NB50 made by ST.


Digi-Key says:
MOSFET N-CH 500V 20A TO-247 made by STMicroelectronics

but they don't stock it.

The NTE cross-reference at
http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search?OpenForm

says you can replace it with an NTE2970, but that doesn't seem to be
stocked either.

Anyone?
