Frequently asked questions
Do I need a resistor with a Zener diode?
In most circuits yes. A series resistor limits the current through the Zener so it stays within its 1 W power rating. Calculate its value from the supply voltage and the required current.
Which Zener voltage should I choose?
The Zener voltage is the regulated voltage across the diode in reverse breakdown. Pick the type that matches your target, for example 5.1 V (1N4733) for a 5 V reference.
