Yes. As Steve said there should be some more on this in the
archives. I have used MOSFETs purely for their inherent diode by
strapping the gate to the source to keep the transistor off. If the
data specs look right then go for it. With a full bridge I guess you
may be doing high freq PWM into an inductive load or motor. In that
case the current is more or less constant in both the diode and
transistor, main power losses are I x V in the diode and I^2 x R in
the transistor. Depending on your control scheme you may have the
option of turning on the MOSFET's that are behaving like diodes and
reduce their power dissipation. Hope this helps.
