Try http://www.cricklewoodelectronics.com for an equivalent (IRFBC40)
Edited: correct link inserted......Sorry! (Alzheimer's wotzis again)

I think that link might be wrong(!), but hopefully a search for the equivalent number will turn up a supplier - as a starting point you could try Farnell (www.farnell.co.uk) or RS (www.rswww.com).
