DESCRIPTION
Using the latest high voltage technology,
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
R
(on) per area, exceptional avalanche and
DS
dv/dt capabilities and unrivalled gate charge and
switchingcharacteristics.
APPLICATIONS
■ HIGHCURRENT, HIGH SPEEDSWITCHING
■ SWITCHMODE POWER SUPPLIES(SMPS)
■ DC-AC CONVERTERS FOR WELDING
