What Is A Gate Resistor. Much like a discharged capacitor, the gate will initially look like a short to ground. Do you need a mosfet gate resistor? The gate electrode in a mosfet is electrically insulated from the main semiconductor by a thin layer of insulating material (typically silicon dioxide, which is similar. And should it go before or after the pulldown resistor (if you have one)? It limits the instantaneous current. A mosfet gate acts as a capacitor, and charging currents can exceed 200ma. The gate resistor will only slow things down by reducing gate drive current, so its optimum value is zero ohms. What value should it be? Its maximum value depends on acceptable switching losses. The gate resistor on a mosfet is really there to protect whatever is sourcing the current. A 100 ohm (3v) to 200 ohm (5v) series resistor keeps this around. Rg is the effective total gate resistance defined as the sum of internal gate resistance rg of the mosfet and any external resistance rgext that.
