Which one is most suitable power device for high frequency (>100 KHz) switching application?
Correct answer: B. Power MOSFET
- A. BJT
- B. Power MOSFET
- C. Schottky diode
- D. Microwave transistor
Explanation
Power MOSFETs are majority-carrier devices, so they switch much faster than BJTs and are well suited to switching frequencies above 100 kHz. A Schottky diode is not itself a controllable switching device.
