zener diode
④ Example electrical devices that zener doide can be used.
A Zener diode used in this way is known as a shunt voltage regulator. In a sense, a
portion of the current through the resistor is shunted through the Zener diode, and the rest
is through the load. Thus the voltage that the load sees is controlled by causing some
fraction of the current from the power source to bypass it—hence the name, by analogy
with locomotive switching points.
Zener diodes in this configuration are often used as stable references for more
advanced voltage regulator circuits. These devices are also encountered, typically in series
with a base-emitter junction, in transistor stages where selective choice of a device
centered around the avalanche/Zener point can be used to introduce compensating
temperature co-efficient balancing of the transistor PN junction. An example of this kind of
use would be a DC error amplifier used in a stabilized power supply circuit feedback loop
system.
