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 RDS(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
