Most likely it is a 2SK2746 MOSFET. The datasheet might give you some
clues:

It's almost certainly a 2SK2746: "Silicon N-channel MOS type field
effect transistor for high speed, high current switching, DC-DC
converter and motor drive applications" according to the info at
www.datasheetarchive.com. Maximum ratings are 800 volts, 7 amps DC,
21 amps pulse, 30 volts on the gate, 150 watts dissipation.

http://www.mark5.co.uk/ seems to have some in stock, but the prices
seem high. DigiKey carries the 2SK2746 but it looks as if they don't
care to sell them in quantities less than 3000 pieces, special-order
only.

It looks to me as if an International Rectifier IRFPE50 might quality
as a substitute (same voltage rating, same threshold-voltage range,
slightly better Rds(on), Id, and Pd ratings) - DigiKey has these in
stock for under $7 each.

One site suggests the SSM09N70F as a substitute.
