Study Notes
MOSFET Characteristics
- MOSFETs have the highest switching speed compared to other devices.
- They are voltage-controlled, meaning they require low control power to operate.
- MOSFETs have simple control circuit requirements, eliminating the need for deep saturation and zero voltage for the off state.
- The negative thermal coefficient of MOSFETs enables equal current division among parallel connected devices.
- Compared to BJTs, MOSFETs have higher conduction losses.
- MOSFETs are available with power ratings ranging from small to small medium, handling currents in the hundreds of amps.
