WebThe choice of gate resistor has a significant effect on the switching delay time. In general, the higher the resistor, the longer the delay time. It is recommended to measure the delay time with a dedicated gate resistor in the application. Figure 4 and Figure 5 show the typical graphs of switching time versus gate resistor.
