Description
This N-channel HEXFET® power MOSFET is produced
using International Rectifier's advanced HEXFET power
MOSFET technology. The low on-resistance and low gate
charge inherent to this technology make this device ideal
for low voltage or battery driven power conversion
applications
The SO-8 package with copper leadframe offers enhanced
thermal characteristics that allow power dissipation of
greater that 800mW in typical board mount applications.
