Features
Very tight variation of on-resistance vs. temperature
Very high operating junction temperature capability (TJ = 200 °C)
Very fast and robust intrinsic body diode
Low capacitance
Applications
Solar inverters, UPS
Motor drives
High voltage DC-DC converters
Switch mode power supplies
Description
This silicon carbide Power MOSFET is produced exploiting the advanced, innovative
properties of wide bandgap materials. This results in unsurpassed on-resistance per
unit area and very good switching performance almost independent of temperature.
The outstanding thermal properties of the SiC material allow designers to use an
industry-standard outline with significantly improved thermal capability. These
features render the device perfectly suitable for high-efficiency and high power
density applications.
