DESCRIPTION
Using the latest high voltage MESH OVERLAY™
process, STMicroelectronics has designed an ad-
vanced family of power MOSFETs with outstanding
performances. The new patent pending strip layout
coupled with the Company’s proprieraty edge termi-
nation structure, gives the lowest R
DS(on)
per area,
exceptional avalanche and dv/dt capabilities and
unrivalled gate charge and switching characteris-
tics.
