FDS6676AS Rev B FDS6676AS 30V N-Channel PowerTrench SyncFET Typical Characteristics (continued) 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 FDS6676AS. Schottky barrier diodes exhibit significant leakage at high temperature and high reverse voltage. This will increase the power in the device. 0.1 IDSS, REVERSE LEAKAGE CURRENT (A) TA = 125oC 0.01 0.8A/DIV 0.001 TA = 100oC 0.0001 TA = 25oC 0.00001 0 5 10 15 20 VDS, REVERSE VOLTAGE (V) 25 30 10nS/DIV Figure 14.
