FDS7066SN3
30V N-Channel PowerTrench SyncFET™
General Description
The FDS7066SN3 is designed to replace a single SO-8 FLMP MOSFET and
Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDS7066SN3 includes an integrated
Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDS7066SN3 as the low-side switch in a synchronous rectifier is close to the performance of the FDS7066N3 in parallel with a
Schottky diode.
Features
19 A, 30 V RDS(ON) = 5.5 mΩ @ VGS = 10 V RDS(ON) = 6.0 mΩ @ VGS = 4.5 V High performance trench technology for extremely low RDS(ON) High power and current handling capability Fast switching FLMP SO-8 package: Enhanced thermal performance in industry-standard package size
