DESCRIPTION
Using the latest high voltage MESH OVERLAY
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 R
per area, exceptional avalanche
DS(on)
and dv/dt capabilities and unrivalled gate charge
and switching characteristics.
APPLICATIONS
■
SWITCH MODE POWER SUPP LIES (SMPS)
■
DC-AC CONVERTERS FOR WELDING
EQUIPMENT AND UNINTERRUPTI BLE
