The working principle of the SMZJ3802AHE3/5B diode can be best explained using an equivalent circuit. The equivalent circuit consists of a voltage source, a series resistor, and a shunt current source in parallel with the zener diode. The zener diode is designed to maintain the current flowing through it even when subjected to large variations in voltage across the diode. This is because the zener diode maintains a constant voltage across it regardless of the applied voltage.

The voltage source provides the current that will flow through the diode and the series resistor determines the voltage that the diode will see. The shunt current source keeps the current at a constant level, even as the voltage across the diode changes. The combination of these elements allows the zener diode to maintain a stable voltage across it.
