How do I wire it to get a stable 3.9V?

Connect the cathode (the banded end) to the positive supply and the anode to ground, with a series resistor to limit current. Zener regulation requires reverse bias, so the cathode must be on the positive side.

What current can it handle?

At 3.9V, a 1W rating corresponds to a maximum of roughly 256 mA (1 W ÷ 3.9 V). Keep the actual power dissipation below the rating, and allow more margin at high ambient temperatures.
