FDS7088SN3
30V N-Channel PowerTrench SyncFETTM
General Description
The FDS7088SN3 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 FDS7088SN3 includes an integrated Schottky diode using Fairchild s monolithic SyncFET technology. The performance of the FDS7088SN3 as the low-side switch in a synchronous rectifier is close to the performance of the FDS7088N3 in parallel with a Schottky diode.

Features
21 A, 30 V RDS(ON) 4.0 m VGS 10 V RDS(ON) 4.9 m 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
