Why it’s tough to characterize SiC power MOSFETs
Switching transients and parasitics can combine to thwart the accurate measurement of important MOSFET operating parameters. Levi Gant, Xuning Zhang, Ph.D., Littelfuse, Inc. Silicon carbide (SiC) power MOSFETs get a lot of attention because they can switch fast while maintaining high blocking voltages. But their superior switching qualities also have potential drawbacks. Parasitic inductances caused […]
New MOSFET package delivers up to 48x power density
Nexperia announced a new package in its MOSFET and LFPAK family which, when combined with its latest silicon technology, results in 40 V MOSFETs delivering a low RDS(on) of 0.7 mΩ. LFPAK88 devices replace larger power packages such as D²PAK and D²PAK-7, and measuring 8 x 8 mm offer a footprint reduction of 60 %, and […]
DC/DC converter ICs include 1.7 kV MOSFET
ROHM announced the availability of AC/DC converter ICs with a built-in 1700V SiC MOSFET, the BM2SCQ12xT-LBZ series. This series is optimized for industrial applications including street lamps, commercial AC systems, and general-purpose AC servos and inverters used in high power equipment.
