IDSS (referred to as the drain current for zero bias) is the maximum current that flows through a FET transistor, which is when the gate voltage, VG, supplied to the FET is 0V.

Is the maximum current flows through a FET transistor, which is when the gate voltage, VG, supplied to the FET is 0v? Please anyone explain me clearly.

When we plot drain characteristics of fet i.e btween Vds and Id when Vgs = 0v we get max value of Id at a point of voltage called pinch off voltage.

As with the decrease in the value of the Vgs the gate to channel junction become reversed biased which resist the flow of current.

with the decrease of Vgs,Id decreaseses.it is max. At 0 Vgs which is Idss
Anu said:   1 decade ago
Id = Idss(1-Vgs/Vp)2.

when Vgs = 0, Id = Idss :) :).
Niket said:   1 decade ago
Id = Idss (1-(Vgs/Vp))2.

If Vgs = 0 then Id = Idss.
