US2421
P-Ch 20V Fast Switching MOSFETs
General Description
The US2421 is the highest performance trench
P-ch MOSFETs with extreme high cell density ,
which provide excellent RDSON and gate charge
for most of the small power switching and load
switch applications.
The US2421 meet the RoHS and Green Product
requirement with full function reliability approved.
