MOSFET vs IGBT difference 1: Construction Right off the bat we can see that the first major difference between the two transistors is their physical construction.

In contrast, bipolar transistors are current-controlled devices. Since very little gate current is required, MOSFETs are fairly easily driven from microprocessors or CMOS logic gates. In a MOSFET, the gate oxide creates a capacitor between the gate and the source, so the steady-state gate current is 0 (although some charging and discharging currents flow when turning-on and turning-off the device). One of the main differences between a MOSFET and a bipolar transistor is that a MOSFET is essentially a voltage-controlled device while and bipolar transistor is a current-controlled device. What is the major difference between MOSFETs and BJTs in regards to how they are controlled? ![]()
