Hi everyone, I have a need for a fast high-current
diode for motor flyback use.

It needs to be very low Vf, fast, and as small and
*cheap* as possible, preferably SMD D-PAK.

One option would be to use a 20A FET in DPAK, which
has an equivalent 20A rated body diode both fast
and low Vf.

Could I just attach the gate pin to the source pin,
keeping the NFET permanently turned off and just use
it as a $0.50 fast small 20A power diode?? Has anyone
done this in a motor power application?
