A certain D-MOSFET is biased at VGS = 0 V. Its data sheet specifies IDSS = 20mA and VGS(off) = -5 V. The value of the drain current is _____________?

Correct answer: A. 20 mA

  • A. 20 mA
  • B. 0 mA
  • C. 40 mA
  • D. 10 mA

Explanation

A depletion MOSFET conducts at VGS = 0 V because its channel exists without gate bias. At this condition, the drain current is the specified IDSS, equal to 20 mA.
