They are rated with a fixed breakdown (avalanche) voltage above which, unlike normal diodes, they'll allow reverse current flow. But how could that be useful I hear you ask?  Protecting micro-controller pins from excess voltage Providing a reference voltage Clamping signal voltages  We stock both 3V3 and 5V Zener diodes as these are the voltages most Raspberry Pi and Arduino projects will run at.  Power: 1.3W Tolerance: ±5%  Here the Datasheet? Get it Here.
