These HEXFET® Power MOSFET's in a Dual SO-8 package

utilize the lastest processing techniques to achieve extremely

low on-resistance per silicon area. Additional features of

these HEXFET Power MOSFET's are a 150°C junction

operating temperature, fast switching speed and improved

repetitive avalanche rating.These benefits combine to make

this design an extremely efficient and reliable device for use

in a wide variety of applications.

The efficient SO-8 package provides enhanced thermal

characteristics and dual MOSFET die capability making it

ideal in a variety of power applications. This dual, surface

mount SO-8 can dramatically reduce board space and is

also available in Tape & Reel.
