The minimum resistance you need and the \$ R_{DS(on)} \$ of the MOSFET you have chosen. The MOSFET's behavior in the linear region though it is similar for almost all the MOSFETs.When using higher gate resistance, switching time becomes longer. As a result, switching loss increases and heat is generated. In the bridge circuit, a short circuit may occur across the upper and lower MOSFETs by combination of the gate resistances.

Among these, the only component that scales as a function of the blocking voltage is the drift region resistance (R Dr ). May 5, 2017 · R DS (on) stands for “drain-source on resistance,” or the total resistance between the drain and source in a Metal Oxide Field Effect Transistor, or MOSFET when the MOSFET is “on.”. R DS (on) is the basis for a maximum current rating of the MOSFET and is also associated with current loss. All things being equal, the lower the R DS (on ... The metal-oxide semiconductor field-effect transistor (MOSFET) is a semiconductor device controllable by the gate signal (g > 0).

For an n-channel MOSFET, the device operates in the first quadrant when a positive voltage is applied to the drain, as shown in figure 2. As the gate voltage (VG) increases above the threshold voltage (VTH), the MOSFET channel begins to conduct current. The amount of current it conducts depends on the on-resistance of the MOSFET, as defined by Like integrated circuit transistors, the on-resistance of individual source cells in a power MOSFET tends to be well matched.
