In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates. destination wedding payment plan

"WebOct 7, 2013 · To use a MOSFET as a switch, you need to ensure that the gate-source voltage (Vgs) is higher than the source voltage. When the gate is connected to the source (Vgs=0), the MOSFET remains off. Take the IRFZ44N, a “standard” MOSFET, as an example. This MOSFET only turns on when Vgs ranges between 10V and 20V.
