| Jun 2, 2016 at 7:29 | comment | added | Bimpelrekkie | Do realize that those 44 ns and 43 ns switching times are for the test conditions as specified in the datasheet. Note how the series resistance through which the gate is charged/discharged is 9.1 ohms. This resistor needs to be low because you want to charge/discharge the gate quickly and that gate behaves as a capacitor of up to a few nF. So up to what frequency you can switch also heavily depends on choosing the proper way to drive the MOSFET. A simple and weak inverter from some logic chip will not cut it ! | |
