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 […]
Specialized diodes, Part 1: Tunnel, Zener/Avalanche, and Schottky diodes
There are diode varieties which do much more than just block current flow in one direction and allow it in the other; some of these special diodes have favorable attributes while others are essential in modern electronics. Every electronic engineer is familiar with the diode: it’s a basic, widely used, two-terminal semiconductor device. The diode’s […]
