WebThe third type of FET operates only in the enhancement mode. This FET has extremely low drain current flow for zero gate-source voltage. Drain current conduction occurs for a VGS greater than some threshold value, VGS(th). For gate voltages greater than the threshold, the transfer characteristics are similar to the depletion/enhancement mode FET. The threshold voltage, commonly abbreviated as Vth or VGS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (VGS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency. When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead. This is somewhat confusing since pinch off applied to insulated-gate fi…

Its usually about 0.5 to 1V for a logic level device. Actually gate threshold voltage is the gate voltage where the device just starts to conduct, perhaps just microamps or milliamps (i.e. threshold of conduction), not it's off voltage. WebNov 28, 2005 · FETs are imperfect devices. Sure they turn on at Vgs but the higher the ACTUAL gate drive voltage the lower the on-resistance. "2.5V Specified" probably means that the on resistance and other parameters were measured/specified with the gate at 2.5V. Many FETs are designed for particular applications.
