■General Description
■Features
The XP133A1145SR is an N-Channel Power MOS FET with low on-state
resistance and ultra high-speed switching characteristics.
Two FET devices are built into the one package.
Low on-state resistance : Rds(on)=0.033Ω (Vgs=10V)
: Rds(on)=0.045Ω (Vgs=4.5V)
Ultra high-speed switching
Because high-speed switching is possible, the IC can be efficiently set
thereby saving energy.
Operational Voltage
: 4.5V
High density mounting : SOP-8
The small SOP-8 package makes high density mounting possible.
