Wether a diode a linear element or not?

Question

Wether a diode a linear element or not?

Answer 1

A diode is a non-linear device.  As you apply a voltage and vary it from zero, the current through the diode in the forward direction increases linear for awhile, then hits a break point where the current flow switches on and increases abruptly.

Answer 2

No.. it is a non linear element.

It allows the flow of current in only one direction.

Others examples include transistors, SCR's...etc

Answer 3

What do you mean by linear but it is a D.C current element
