MOSFET → Majority carrier device (NMOS, PMOS)
Diode → both majority & minority carrier device
Transister → Npn, pnp
IGBT → input is MOSFET, Output is BJT
Diode → both majority & minority carrier device
Transister → Npn, pnp
IGBT → input is MOSFET, Output is BJT

Power Semiconductor Devices: IGBT, MOSFET, Diode and Thyristor
Majority and Minority Carrier Devices:
- Majority carrier devices: Conduct electricity mainly by the flow of majority carriers (electrons in N-type and holes in P-type).
- Minority carrier devices: Conduct electricity mainly by the flow of minority carriers (holes in N-type and electrons in P-type).
Statement:
D) MOSFET is a majority carrier device, whereas IGBT, Diode, Thyristor are minority carrier devices.
Explanation:
MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a majority carrier device as it operates mainly on the principle of controlling the flow of majority carriers (electrons). It is a voltage-controlled device that has a gate terminal, which is insulated from the channel formed by the source and drain terminals.
IGBT (Insulated Gate Bipolar Transistor) is a minority carrier device as it operates mainly on the principle of controlling the flow of minority carriers (holes). It is a voltage-controlled device that combines the advantages of MOSFET and BJT (Bipolar Junction Transistor).
Diode is a minority carrier device as it conducts mainly by the flow of minority carriers (holes in N-type and electrons in P-type). It is a two-terminal device that allows current to flow in one direction only.
Thyristor is a minority carrier device as it operates mainly on the principle of controlling the flow of minority carriers (holes). It is a four-layer device that has three terminals (anode, cathode, and gate) and allows current to flow in one direction only.
Conclusion:
Thus, option D is the correct statement as MOSFET is a majority carrier device, whereas IGBT, Diode, and Thyristor are minority carrier devices.

For the power semiconductor devices IGBT, MOSFET, Diode and Thyristor,...
BJT is bipolar thats simple , diode is also bipolar , it too has hole and electrons , now your only confusion must be on why IGBT is bipolar not unipolar although construction wise it is similar to mosfet , and operation wise too . I too had this confusion , In construction of IGBT the last layer is N+ , P , N- , P+ ) whereas that of mosfet is ( N+ , P , N- and N+ ) so you see the last layer N+ is changed with p+ , due to this change , now IGBT also has a small minority carrier conductivity , due to this reason IGBT becomes Bipolar , but Mosfet remains unipolar . And basically due to having no minority problem Mosfet turn off time is lower , recovery time is reduced which results in greater switching speed then IGBT
