FDR8305N

FDR8305N Dual N-Channel 2.5V Specified PowerTrench MOSFET General Description Features These N-Channel 2.5V specified MOSFETs are produced using Fairchild Semiconductor's advanced PowerTrench process that has been especially tailored to minimize the on-state resistance and yet maintain low gate charge for superior switching performance. • • Low gate charge (16.2nC typical). Applications • Fast switching speed. • • • • High performance trench technology for extremely low RDS(ON). • Small footprint (38% smaller than a standard SO-8);low profile package (1 mm thick); power handling capability similar to SO-8. Load switch Motor driving Power Management D2 4.5 A, 20 V. RDS(ON) = 0.022 Ω @ VGS = 4.5 V RDS(ON) = 0.028 Ω @ VGS = 2.5 V.

RθJA 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. RθJC is guaranteed by design while RθCA is determined by the user’s board design. Both devices are assumed to be operating and sharing the dissipated heat energy equally.
