Identify the correct statement related to switching speed of the BJT.

The correct answer is option 3.

MOSFETs generally switch faster than BJTs due to their unipolar nature and the control method used to switch them. MOSFETs rely on a voltage to control the channel and only involve majority carriers, leading to faster on and off times. BJT switching, on the other hand, involves minority carriers and is more susceptible to recombination effects, resulting in slower turn-off times. 

Differences between BJT and MOSFET

• Construction: BJTs are bipolar junction transistors, and MOSFETs are metal-oxide-semiconductor field-effect transistors. BJTs have three terminals: the emitter, base, and collector. MOSFETs have only three terminals: the source, gate, and drain
• Operation: BJTs operate by controlling the flow of current between the emitter and collector, while MOSFETs control flow of current between the source and drain
• Switching speed: BJTs are slower, whereas MOSFETs are faster.
• Power consumption: BJTs consume more power, and MOSFETs consume less power.
• Temperature sensitivity: BJTs are more temperature-sensitive than MOSFETs
