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 […]
