General Description
The advanced power MOSFET provides the designer
with the best combination of fast switching,
ruggedized device design, low on-resistance and
cost-effectiveness.
The SOP-8 package is universally preferred for all
commercial-industrial surface mount applications and
suited for low voltage applications such as DC/DC
converters.
