The model resistor value is obtained by dividing the voltage at the operating point by the current at ...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. explosion saltimmunization records kansas Example of practical diode model.
