Working Principle of CMDZ5257B BK

The working principle of CMDZ5257B BK is based on the zener effect. When forward biased, the component allows current to flow from the anode to the cathode. When reverse biased, the component will breakdown at a certain voltage, creating an avalanche effect that leads to a heavy current flow from the cathode to the anode. This is known as the zener effect. The breakdown voltage of the component is known as the zener voltage and is typically greater than the forward voltage drop. The component can also be used for temperature compensation, as the zener voltage is affected by temperature fluctuations.
