About this product
A 12 V Zener diode rated for up to 1 W total power dissipation, used to create a fixed reference voltage or to stabilise voltage in low-current circuits. The listing specifies 10 µA maximum reverse leakage and a 1.2 V forward drop. It is normally used with a series resistor that limits the current through the diode.

How is a Zener diode used to regulate voltage?
It is connected in reverse bias across the load, with a series resistor feeding it from the supply. The diode holds the voltage near 12 V as long as its current stays within the rated range.
Does the supply voltage need to be above 12 V?
Yes. The supply must be higher than the 12 V Zener voltage, with enough headroom for the series resistor to drop the difference and still deliver the current your load needs.
