Deja vu- I remember saying the exact thing about the IRF3703, amazing disbelief, and then saw the pkg was limited to 75 amps. As such I don't know why they bother to list a spec that the part cannot handle.
What are you trying to switch? There are some super hexfets that switch large currents and they're fairly cheap. There are some in SO-8 pkgs that can handle 16 amps constant current each due to their amazingly low rds-on, without a heatsink, for around $1. Of course their low rds-on won't help with switching losses and they don't have as much heat dissipating capabilities to handle switching loss heat.
