DESCRIPTION
Using the latest high voltage MESH OVERLAY
TM
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 switching characteristics.
