AO4240
40V N-Channel MOSFET
General Description
The AO4240 uses trench MOSFET technology that is
uniquely optimized to provide the most efficient high
frequency switching performance.Power losses are
minimized due to an extremely low combination of
R
DS(ON)
and Crss. In addition,switching behavior is well
controlled with a "Schottky style" soft recovery body
diode.
