DESCRIPTION
Using the latesthigh voltage MESHOVERLAY
process, SGS-Thomson has designed an advanced family of power MOSFETs with outstanding performances. The new patent pending strip
layout coupled with the Company’s proprietary
edge termination structure, gives the lowest
RDS(on) per area, exceptional avalanche and
dv/dt capabilities and unrivalled gate charge and
switchingcharacteristics.
APPLICATIONS
■ HIGHCURRENT, HIGH SPEEDSWITCHING
■ SWITCHMODE POWERSUPPLY (SMPS)
■ DC-AC CONVERTERFOR WELDING
