s TYPICAL RDS(on) = 0.11
s EXTREMELY HIGH dv/dt CAPABILITY
s ± 30V GATE TO SOURCE VOLTAGE RATING
s 100% AVALANCHE TESTED

DESCRIPTION
Using the latest high voltage MESH OVERLAY
process, SGS-Thomson has designed an ad-
vanced family of power MOSFETs with outstand-
ing 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
switching characteristics.
APPLICATIONS
s HIGH CURRENT, HIGH SPEED SWITCHING
s SWITCH MODE POWER SUPPLY (SMPS)
s DC-AC CONVERTER FOR WELDING
