How zener diode behaves as a voltage regulator?

In: Electronics [Edit categories]

Answer:

The zener diode behaves as a voltage regulator because, in the reverse bias condition, it has a relatively flat voltage to current curve. That means that the voltage across the diode will be relatively constant even if the current through it varies slightly. In order to achieve stable operation, you should operate in the normal "expected" current range. You get that from the specifications.
