QM4306S
N-Ch and P-Ch Fast Switching MOSFETs
General Description
The QM4306S is the highest performance trench
N-ch and P-ch MOSFETs with extreme high cell
density , which provide excellent RDSON and gate
charge for most of the synchronous buck converter
applications .
The QM4306S meet the RoHS and Green Product
requirement 100% EAS guaranteed with full
function reliability approved.
