This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDD6680AS includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDD6680AS as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDD6680A in parallel with a Schottky diode. ## **Applications** **==> picture [50 x 8] intentionally omitted <==** **----- Start of picture text -----**
