Dual N-Channel 2.5V Specified PowerTrench MOSFET
General Description
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.
Features *
4.5 A, 20 V. RDS(ON) = 0.022 @ VGS = 4.5 V RDS(ON) = 0.028 @ VGS = 2.5 V.
* * * *
Low gate charge (16.2nC typical). 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.
Applications * * *
Load switch Motor driving Power Management

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. RJC is guaranteed by design while RCA is determined by the user's board design. Both devices are assumed to be operating and sharing the dissipated heat energy equally.

Packaging Description:
SSOT-8 parts are shipped in tape. The carrier tape is made from a di ssipat ive (carbo n filled) po ly carbon ate resin. The cover tape is a multilayer film (Heat Activated Adhesive in nature) primarily composed of polyester film , adhesive layer, sealant, and anti-static sprayed agent. These reeled parts in standard option are shipped w ith 3,000 units per 13" or 330cm diameter reel. The reels are dark blue in color and is made of polystyrene plastic (antistatic coated). Other option comes in 500 unit s per 7" or 177cm diameter reel. This and some other options are further described in the Packagin g Information table. These full reels are in di vidu ally barcod e labeled and placed inside a standard intermediate box (ill ustrated in figure 1.0) made of recyclable corrugated brow n paper. One box contains two reels maximum. And t hese boxes are placed ins ide a barcode labeled shipp ing bo x whic h comes in di fferent sizes depend in g on t he nu mber of parts shippe d.
