Working Principle

The working principle of a Zener diode is based on the reverse breakdown mechanism of a PN junction diode. When the reverse voltage across the diode exceeds the breakdown voltage, a large current flow occurs. This reverse current, which is known as a Zener current, flows in the reverse direction and keeps the diode in reverse breakdown even if the external bias voltage changes.

The breakdown voltage of the CMZ5943B BK is maintained within a very small tolerance range of ±3%. This allows for very precise control of the output voltage. The device has a low dynamic impedance, which makes it suitable for high speed operation in transient conditions.
