WebJun 12, 2024 · Qg (total gate charge ) is 71nC at 10V. So if i divide 71nC by 10V i should get an equivalent capacitor at the gate. At least that is what I think. (and if this is wrong everything that follows consequently is also wrong) However further down the datasheet input capacitance is given at 1960 pF. WebAs seen in Figure 1, a large Gate voltage is required for large current flow. Although the models listed in Table 1 feature a threshold value less than 2.5V, 4V drive is recommended. Always make sure there is a sufficient Gate voltage to turn the MOSFET ON.
