Description. The diode is a semiconductor device that is controlled by its own voltage Vak and current Iak. When a diode is forward biased (Vak > 0), it starts to conduct with a small forward voltage Vf across it. It turns off when the current flow into the device becomes 0. When the diode is reverse biased (Vak < 0), it stays in the off state. The ideal diode i-v characteristic curve is shown below: Figure \(\PageIndex{1}\): Ideal diode equation.
