1N5226 3.3V 500mW Zener Diode DO-41
A Zener diode is a special kind of diode which allows current to flow in the forward direction like a regular diode, but also allows it to flow in the reverse direction when the voltage is above a certain value. This is known as the 'breakdown voltage'. That means you apply voltage across them, and when a preset voltage is reached, they start conducting. A common analogy is a 'pressure relief valve'. They have lots of uses, especially in safety circuits where you want to make sure a voltage signal doesn't exceed a limit that might damage the circuit.
This 1N5226 zener diode is set at 3.3V, making it ideal for protecting the inputs of a 3.3V circuit.
Zener diodes are often used to stabilize and clip circuits.
The 1N5226 is a 3.3V Zener Diode, meaning it has a breakdown voltage of 3.3V.
