AOD242
40V N-Channel MOSFET
General Description
Product Summary
The AOD242 uses trench MOSFET technology that is
uniquely optimized to provide the most efficient high
frequency switching performance. Both conduction and
switching power losses are minimized due to an
extremely low combination of R_DS(ON), Ciss and Coss.
This device is ideal for boost converters and synchronous
rectifiers for consumer, telecom, industrial power supplies
and LED backlighting.
