The body diode forward voltage and current carrrying capability are not parameters we characterize for our devices. If VOUT > VIN, it can be assumed that reverse current will flow through the device. If a device with reverse current blocking is needed, ...
MOSFET Body Diode Joey White Hephaestus Audio The body diode of a typical MOSFET is very slow. In order to maintain fast switching for high-efficiency, it is necessary to select MOSFETs with fast intrinsic body diodes, or to add additional circuitry to ensure the body diode will never conduct...
However, in a SiC p-i-n diode, forward current stress causes reliability degradation due to expansion of the electron-hole recombination-induced stacking faults. Applying the process optimization of the epitaxial layer for the reduction of recombination-induced stacking faults and the body diode ...

voltage equal to the forward voltage VF across the body diode. Next, when Q2 turns on again, the current starts flowing through Q2 and the body diode of Q1 enters reverse recovery, causing its drain-source voltage to rise sharply. The rate of change of the drain-source voltage equals the...

The graph below shows the Vds-Id characteristics of a SiC-MOSFET. With the source as reference, a negative voltage is applied to the drain, and the body diode is in a forward-biased state. In the graph, the green trace for which Vgs = 0 V shows what is essentially the Vf characterist...
