Frequently asked questions
How do I use it as a voltage reference?
Connect it in reverse bias through a series resistor from the supply. The resistor value depends on supply voltage and load current, so calculate it for your circuit.
Is this the same as the 5V listing?
The listing states 5V. The standard designation for this SOT-23 Zener in the 5 V class is BZX84C5V1 (5.1 V nominal), so confirm the marking and datasheet before using it in a precision circuit.
