International Rectifier IRF7705 Datasheet

l Ultra Low On-Resistance
l P-Channel MOSFET
l Very Small SOIC Package
l Low Profile ( < 1.2mm)
l Available in Tape & Reel

Description

HEXFET® power MOSFETs from International Rectifier
utilize advanced processing techniques to achieve ex­tremely low on-resistance per silicon area. This benefit,
combined with the ruggedized device design, that Inter­national Rectifier is well known for,

signer with an extremely efficient and reliable device
for use in battery and load management.

The TSSOP-8 package has 45% less footprint area than
the standard SO-8. This makes the TSSOP-8 an ideal
device for applications where printed circuit board space
is at a premium. The low profile (<1.2mm) allows it to fit
easily into extremely thin environments such as portable
electronics and PCMCIA cards.
