The BSP129 MOSFET, available from Digi-Key, should do the job. Max drain voltage is 240, drain current 200 mA max, Ton = 6 nS max. You could drive from logic, except it requires a negative bias to turn it off, but you could offset the logic supply.
The data sheet is at: http://rocky.digikey.com/WebLib/Infineon/Web%20Data/BSP129.pdf
BTW, Digi-Key has a good search engine, when you are looking for parts. www.digikey.com
