STP9547 P Channel Enhancement Mode MOSFET - 6.8A DESCRIPTION The STP9547 is the P-Channel logic enhancement mode power field effect transistor is produced using high cell density, DMOS trench technology. This high density process is especially tailored to minimize on-state resistance. These devices are particularly suited for low voltage application such as cellular phone and notebook computer power management and other batter powered circuits where high-side switching. FEATURE PIN CONFIGURATION SOP-8 -40V/-5.6A, RDS(ON) = 55m @VGS = -10V -40V/-5.2A, RDS(ON) = 80m @VGS = -4.5V Super high density cell design for extremely low RDS(ON) Exceptional on-resistance and maximum DC current capability SOP-8 package design PART MARKING SOP-8 ORDERING INFORMATION Part Number Package Part Marking STP9547S8RG SOP-8P STP9547STP954
