How do I wire this diode for voltage regulation?
Connect it in reverse bias: the cathode (black band) goes to the positive rail and the anode to ground. Place a series resistor before it to limit current, sized for the Zener current you need, and keep the dissipation within the 500 mW rating.
Can it regulate a 5V rail?
No. Its nominal voltage is 3.9V, so it does not suit a 5V rail. Choose a Zener diode whose nominal voltage matches the level you need.
