Gate Driver & Short-Circuit Protection of Silicon Carbide …
As silicon carbide MOSFET has less short circuit withstand time than IGBT, DESAT threshold voltage should be set lower for silicon carbide MOSFET than IGBT to shorten blanking time. Except for changing the resistance value and the nuer of dials, a resistor divider can be used to modify the saturation circuit for low threshold voltage.

Know Rotary Saw Blades - Fire Rescue Magazine
2008/9/30· Silicon carbide discs are made to cut concrete, as well as stone, brick, soft aggregate and masonry—materials we encounter when performing forcible entry and often on flat roofs. These discs are fairly inexpensive (usually under $20) and, as with all abrasive discs, wear out rather quickly and will need to be replaced during an emergency if many cuts are required.
