SOP-8
Description:
The WTK9431 provide 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.
