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 FDS6699S. Schottky barrier diodes exhibit significant leakage at high temperature and high reverse voltage. This will increase the power in the device. 0.1 I DSS, REVERSE LEAKAGE CURRENT (A) T A = 125 oC 0.01 CURRENT : 0.8A/div T A = 100 oC 0.001 0.0001 TA = 25 oC 0.00001 0 5 10 15 20 VDS, REVERSE VOLTAGE (V) 25 30 TIME : 12.5ns/div Figure 13.
