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 R DS(on) per area,
exceptional avalanche and dv/dt capabilities and
unrivalled gate charge and switching characteris-
tics.

APPLICATIONS
s HIGH CURRENT, HIGH SPEED SWITCHING

s SWITH MODE POWER SUPPLIES (SMPS)

s DC-AC CONVERTERS FOR WELDING
