About this product

The 1N5248B is an 18 V, 0.5 W Zener diode used for voltage regulation and reference in low-power circuits. Once reverse breakdown voltage is reached it conducts in reverse, holding the voltage across it near 18 V. It is commonly used in simple shunt regulators, voltage clamps and reference circuits.

How do I connect it as a simple 18V regulator?

Connect the diode in reverse bias: the cathode (banded end) to the positive rail and the anode to ground. Put a series resistor between the supply and the diode, sized so the diode current stays within its 0.5 W power rating.

Does the polarity matter?

Yes. A Zener diode must be connected in reverse for regulation, so the band marking the cathode must go to the more positive side of the circuit. Connecting it forward behaves like a normal diode and gives no regulation.
