Choosing the right semiconductor device becomes easier when you see how each one controls current and power.
✨✨A BJT is a current-controlled device where a small base current regulates a larger collector current, making it useful for amplification and basic switching.
✨✨An FET is voltage-controlled, so the gate voltage changes channel resistance with almost no input current, which improves efficiency and input impedance.
✨✨An IGBT combines the easy gate control of a FET with the strong output handling of a BJT, making it common in motor drives and high-power converters.
✨✨A thyristor works differently: a short gate pulse turns it ON, and it stays latched until current drops below a limit, which is ideal for controlled rectifiers and AC power control.
Seeing these differences side by side builds clear intuition about when to use each device in real electronic and power circuits.
