Mosfet drain to source capacitance (URGENT!!!)

[olemp]

hi.....
what is the drain to source capacitance of the irf840....
**broken link removed**

in data sheet there is a parameter named:
Output Capacitance : Coss

is this same thing with the drain to source capacitance of the mosfet (Cds)...

i am designing a resonance ZVS dc-dc converter and i need the Cds value of the irf840 to design resonance circuit.............

thanks in advance,

isa
