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 R
DS(on)
per area, exceptional avalanche
and dv/dt capabilities and unrivalled gate charge
and switching characteristics.
APPLICATIONS
