FDS7698S Rev C1 (W)
Typical Characteristics : Q2
SyncFET Schottky Body Diode
Characteristics
Fairchild’s SyncFET process embeds a Schottky diode
in parallel with PowerTrench MOSFET. This diode
exhibits similar characteristics to a discrete external
Schottky diode in parallel with a MOSFET. Figure 12
shows the reverse recovery characteristic of the
FDQ7698S Q2.
TIME : 12.5ns/div
C
Figure 12. FDQ7698S SyncFET body diode
reverse recovery characteristic.
For comparison purposes, Figure 13 shows the reverse
recovery characteristics of the body diode of an
equivalent size MOSFET produced without
SyncFET(FDS6676).

Diode reverse recovery characteristic.
Schottky barrier diodes exhibit significant
leakage at high temperature and high reverse
voltage. This will increase the power in the
device.
