Typical Characteristics
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 14 shows the reverse recovery
characteristic of the FDMS3008SDC.

Schottky barrier diodes exhibit significant leakage at high tem-
perature and high reverse voltage. This will increase the power
in the device.
