Figure 3 Gate-source threshold voltage range of SiC MOSFET The minimum gate-source threshold voltage V gs(th) of other SiC MOSFET devices can be lower than 2 V at 25°C in some cases. Therefore, minor ground bouncing can lead to an uncontrolled turn-on of the MOSFET when using an off-state voltage of zero Volts.
