Working principle

The 1N4733A-T diode is a P-N junction diode with a breakdown voltage of 3.3V. When it is connected to a power source, the P-N junction of the diode will conduct electric current and the voltage across the diode would be a constant 3.3V. This is the Zener effect.

If the anode of the diode is connected to a higher voltage than 3.3V, then the diode will act as a voltage regulator and regulate the output voltage. If the anode is connected to a lower voltage, then the diode will not conduct and no current would flow.

The 1N4733A-T can also be used to protect circuits from overvoltage. When the voltage at the anode of the diode exceeds the breakdown voltage of the diode, the diode will conduct current and the excess voltage will be dissipated as heat. This will protect the circuit from overvoltage.
