WebFigure 1 shows the gate charge typ- ical characteristic curve for the same MOSFET as it varies with gate voltage and drain voltage. Make sure the gate charge value you use for calculating power dissipation fits the conditions of your application. Web(1) The switching characteristics of both turn-on and turn-off are dependent on the value of R G , and therefore the greater the R G the longer the longer the switching time and the greater the switching loss. Also, as R G increases, the surge voltage during switching becomes smaller. (2) The greater the R G
