Explain the series and parallel operation of MOSFET. Which is suitable and why?

1 Answer

Series operation of MOSFET:

To increase voltage handling capability MOSFETs are connected in series. When the MOSFETs are connected in series each MOSFET should turn on and turn off simultaneously otherwise if one MOSFET is in on or off state and other MOSFETs is in off or on state then it may destroy the MOSFET because of high voltage.




Parallel operation of MOSFET:

To increase current handling capability MOSFETs are connected in parallel. In parallel operation of MOSFET should have same gain, turn on and turn off time and transconductance. Each MOSFET should share current equally.
