FDC638APZ
P-Channel 2.5V PowerTrench ? Specified MOSFET
–20V, –4.5A, 4 3 m ?
Features
Max r DS(on) = 4 3 m ? at V GS = –4.5V, I D = –4.5A
Max r DS(on) = 6 8 m ? at V GS = –2.5V, I D = –3.8A
Low gate charge ( 8 nC typical).
High performance trench technology for extremely low r DS(on).
SuperSOT TM –6 package:small footprint (72% smaller than
standard SO–8) low profile (1mm thick).
RoHS Compliant
General Description
This P-Channel 2.5V specified MOSFET is 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
These devices are well suited for battery power applications:load
switching and power management,battery charging circuits,and
DC/DC conversion.
