The MOSFET was invented by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959. It was a breakthrough in power electronics. Generations of MOSFETs enabled power designers to achieve performance and … See more

Because of their unipolar nature, the power MOSFET can switch at very high speed. Indeed, there is no need to remove minority carriers as … See more

The equivalent circuit for a power MOSFET consists of one MOSFET in parallel with a parasitic BJT. If the BJT turns ON, it cannot … See more

Cellular structure
As described above, the current handling capability of a power MOSFET is determined by its … See more

The power MOSFET is the most widely used power semiconductor device in the world. As of 2010 , the power MOSFET accounts for 53% of the power transistor market, ahead of the See more

Several structures had been explored in the 1970s, when the first commercial power MOSFETs were introduced. However, most of … See more

Gate oxide breakdown
The gate oxide is very thin (100 nm or less), so it can only sustain a limited voltage. In the datasheets, manufacturers often state a … See more
