DESCRIPTION
Using the latesthigh voltage MESH OVERLAY
process, STMicroelectronics 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 SPEED SWITCHING
■ SWITCHMODE POWER SUPPLY (SMPS)
■ DC-AC CONVERTERFOR WELDING
