Frequently asked questions
How do I wire it as a voltage reference?
Connect it in reverse bias, cathode to the positive rail and anode to ground, through a series resistor. The resistor limits the current, and the diode holds about 2.4 V across its terminals.
What is the maximum current it can handle?
At full rated power the limit is about 0.5 W divided by 2.4 V, which is roughly 200 mA. Choose the series resistor so the current stays below that and the diode does not overheat.
