FDS7098N3
30V N-Channel PowerTrench ® MOSFET
General Description
This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for low gate charge, low RDS(ON) and fast switching speed.
Features
· 14 A, 30 V RDS(ON) = 9 m @ V GS = 10 V RDS(ON) = 12 m @ V GS = 4.5 V
Applications
· · · DC/DC converter Power management Load switch
· 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

Notes: 1. RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. R JC is guaranteed by design while R CA is determined by the user's board design.
