WebDec 19, 2016 · In an enhancement mode FET (whether P or N channel), the VGS (voltage) turns on current flow. If VGS = 0 V then no current flows from drain to source. You will sometimes see this described as 'Normally Off' In a depletion mode FET (whether P or N channel), the VGS (voltage) turns off current flow. WebWhen the voltage from gate to source is zero, the n-channel enhancement-mode MOSFET acts as an open-circuit. Thus, enhancement-mode devices are referred to as normally off …
