WebMay 9, 2024 · MOSFET in saturation region is preferred to make it work as a switch. It's because it's written by someone who thinks that the name of the equivalent section of the BJT's characteristic is 100% transferable to MOSFETs. To clear this up: - When a MOSFET is operated as an on -switch it works in the triode or ohmic region WebMay 14, 2024 · BJT can switch faster than MOSFET due to the less capacitance at the control pin. However MOSFET is more tolerant to heat (stable to thermal changes) and can simulate a good resistor.”. So, to answer your question, a “BJT can switch faster than MOSFET due to [there being] less capacitance at the control pin.”.
