How do I wire it as a 3.3V voltage reference?
Connect the cathode (the banded end) to the positive rail and the anode to ground, so the diode is reverse-biased. Use a series resistor from the supply to limit current, and keep the total power within the 0.5 W rating.
How do I identify the polarity of the diode?
The cathode end is marked with a band. In the reverse direction it holds its voltage near 3.3 V; if installed the other way it behaves like a normal forward-biased diode at about 0.6 to 0.7 V.
