DESCRIPTION
Using the latest high voltage MESH OVERLAYTM
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- INTERNAL SCHEMATIC DIAGRAM
nation structure, gives the lowest RDS(on) per area,
exceptional avalanche and dv/dt capabilities and
unrivalled gate charge and switching characteris-
tics.
APPLICATIONS
