Trailing edge dimmer circuit limitations
You can certainly use a FET and AC bridge to switch a load, but not blindly consider leading or trailing edge dimming on any load with reactance. A zero-crossing trigger Triac is the best switch for minimum surge current and low current cut-off. Phase controlled dimming is a reactance issue , specific for each type.
But unless you have a specific load for a leading-edge zero-crossing trigger with mid-phase cut-off, this application has inductive load issues!

RdsOn 0.19 Ω max @ 25'C
RdsOn 0.43 Ω typ @ 125'C
... thermal parameters require adequate sink for Rja =  ~ 1 'C/W best ~
EAS 690 mJ abs. max.
EAR 1 mJ abs. max.
I pulse  62 A  limited by T
I(AR)  20 A   . . .  &quot;
With these parameters you can choose what is your maximum reactive energy load L or C and real energy load R for the best possible heatsink. (CPU + fan)
Consider AC motors typ. have peak surge current of 8x rated max current and light bulbs have a worst-case peak sine current on start ~ 10x rated.
Reply to previous comments:
For a std 6A Triac 100uA typ. @ 600V you can suppress the leakage below LED visible threshold with 3.3M shunt R to 0V (1/16thW) on 240Vac and perhaps tiny RF cap.But only on dimmable LED lamps.
Or you may consider to use an Alternistor (snubberless) (matched to load) .
Right , the FET diode is across the Vds switch  and not across load for Drain switched loads. Like a motor (ok on some) or some transformers not rated for dI/dt switching on primary  and might fail from eddy current losses and mid-current flyback damage.
