Dynamic reverse bias sic

Weband with no bias on the gate, no channel is formed under the gate at the surface and the drain voltage is entirely supported by the reverse-biased body-drift p-n junction. Two related phenomena can occur in poorly designed and processed devices: punch-through and reach-through. Punch-through is observed when the depletion region on the source side WebThe first part is the dc characteristics of 4H-SiC PiN diodes. During the reverse bias operation, the material parameters of the drift region are selected to achieve a target blocking voltage of 6.5 kV. However, during the forward bias operation, once conductivity modulation occurs in the drift region, the on-voltage drop will be reduced.
