Difference Between MOSFET / IGBT / SCR

Question

Accepted Answer

MOSFET, IGBT, and SCR are all types of power semiconductor devices used for switching applications.

MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled device with high switching speed and efficiency.
IGBT (Insulated Gate Bipolar Transistor) combines the advantages of MOSFET and bipolar transistor, suitable for high power applications.
SCR (Silicon-Controlled Rectifier) is a current-controlled device used for high power rectification and AC power control.
MOSFET is commonly used in low to medium power applications like amplifiers and power supplies.
IGBT is used in high power applications such as motor drives and inverters.
SCR is used in applications requiring high current and voltage handling like industrial heating and lighting control.
