Characteristics
Fairchild’s SyncFET process embeds a Schottky diode
in parallel with PowerTrench MOSFET.
exhibits similar characteristics to a discrete external
Schottky diode in parallel with a MOSFET. Figure 12

For comparison purposes, Figure 13 shows the reverse
recovery characteristics of the body diode of an
equivalent size MOSFET produced without SyncFET
(FDP6035AL).
