Principle The sharp increase in the characteristic current-voltage curve
for Zener diodes above the breakdown voltage makes it
suitable for stabilising small direct voltages. When the input
voltage is increased beyond the breakdown voltage, the current
increases sharply while the diode resistance gets smaller and
smaller. Therefore, the voltage at the Zener diode remains
nearly constant. Benefits
Tasks How can a Zener diode be used to stabilise direct voltage? Investigate the functioning of a voltage stabiliser with a Zener diode.
