Mosfet normally on mode

WebThe similarities go beyond these surface issues. Both MOSFETs and enhancement-mode GaN devices are normally off and are voltage-driven devices (not current-driven) with an input capacitance that must be properly charged/discharged by their driver. The slew rate and shape of this charge/discharge drive waveform is an important factor in performance.
