Sine waves have predictable shape and timing so rise/fall time (10-90%) can be calculated fairly easy.

RiseTime = (arcsin(0.8))/(PII*Freq) = ~0.2952/Freq -> ~0.3*Period
RiseTime = 74ns * 0.3 = ~22ns

Your FET rise/fall time need to be faster that 22ns.

If you do a google search the device is manufactured by Supertex which has tech support: http://www.supertex.com/contact_app_engineer.html . There are also several sites that show equivelent devices as well as this site which shows who has a supply of the devices: http://www.ic2ic.com/search.jsp?sSea...106N5&prefix=V .
