<---Doesn't it suck they don't give you the complete picture? Duty cycle is generally related to transistor junction temperature rise over a given period of time. I guess you could always look up the transistor spec's and see what they spec as a safe junction temperature. Of course you could always ask the manufacturer if they guarantee that duty cycle..
