Abstract
A circuit model of a Zener diode includes a forward bias diode, a reverse bias diode, a first resistor, a second resistor, and a voltage source. The forward bias diode and the first resistor are connected in series and form a first branch disposed between a positive terminal and a negative terminal. The voltage source, the reverse bias diode and the second resistor are connected in series and form a second branch, which is disposed between the positive terminal and the negative terminal and connected in parallel with the first branch. The circuit model can specifically describe the current-voltage characteristics of the Zener diode and significantly improve the accuracy of the circuit simulation.
