Metric · Power & Discretes
Critical breakdown field
The peak electric field a semiconductor can sustain before avalanche multiplication causes breakdown, expressed in megavolts per centimetre. A higher value lets a device block the same voltage across a thinner, more heavily doped drift region.

Notes
SiC's roughly tenfold advantage over silicon translates into about a hundredfold reduction in specific on-resistance.
