How do I connect it as a voltage regulator?
Connect it in reverse bias, with the cathode to the positive rail and the anode to ground, through a series resistor. Size the resistor so the current stays within the diode's power rating.
Can I use this diode for a 5 V or 12 V rail?
No. This part regulates at a nominal 30 V. For a different voltage, choose a Zener from the same series whose nominal voltage matches your target.
