WebA MOSFET can also be used for switching larger currents based on a small input signal. This can be particularly useful when switching larger loads from a microcontroller or … WebBut I can agree that those points don’t really apply to a timy BSS138. Also the resistance is to high for my taste. You can approximate the switching time with tau = R * C where C is the total Gate capacitance. Up to 10 nF for big MOSFETs. Imho a switching time of 500 ns to 1 us is a good compromise between EMC and switching losses.
