SiC MOSFETs have a lower RDS(on) than Si MOSFETs. They are normally driven at a higher gate voltage, typically –5 V to 20 V, to enhance RDS(on) and switching speed. The body diode of a SiC MOSFET has a high voltage drop (about 4 V), but a low minority carrier lifetime. They have a significantly faster recovery and a lower recovery charge than ...

To understand the MOSFET, we first have to analyze the MOS capacitor, which consti-tutes the important gate-channel-substrate structure of the MOSFET. The MOS capacitor is a two-terminal semiconductor device of practical interest in its own right. As indi-cated in Figure 1.2, it consists of a metal contact separated from the semiconductor by

The operation of the enhancement-mode MOSFET, or e-MOSFET, can best be described using its I-V characteristics curves shown below. When the input voltage, ( V IN) to the gate of the transistor is zero, the MOSFET conducts virtually no current and the output voltage ( V OUT) is equal to the supply voltage V DD.So the MOSFET is "OFF" operating within its …
