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