Yes it can be done.
Usually, this type of diode is called zener shunt voltage regulator or shunt references; it can be a 2 or 3-terminal device.
Two terminal devices rely only on the zener b2b tunneling quantum breakdown effect for generating a fixed voltage drop.
Three terminal devices work in closed loop: you put a voltage divider at the output and feed the divided voltage to the additional "control terminal", so that a closed loop is used to compensate temperature and load variations. You can check LM4041 datasheet as an example.

What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
Which region zener diode can be used as regulator?
Reverse Bias
Which type of diode used in bridge rectifier?
You can use most diodes for that purpose, and particularly silicon diodes. However, you should not use zener diodes and similar for rectification purposes. Otherwise, you will likely not get the intended result. If the voltage exceeds the avalanche voltage, then the zener diode will no longer rectify, but conduct the other way as well.
How is zener diode different from p-n junction diode?
A p-n junction diode is made of a crystal of semiconductor. Impurities are added to it to create a region on one side that contains negative charge carriers (electrons), called n-type semiconductor, and a region on the other side that contains positive charge carriers (holes), called p-type semiconductor. A Zener diode contains a heavily doped pn junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material. A reverse biased Zener diode will exhibit a controlled breakdown and let the current flow to keep the voltage across the Zener diode at the Zener voltage.
Can zener diode used as rectifier?
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
Does a zener diode acts as a switch?
A zener diode cannot be used as switch.
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
How is AC converted to DC and does it change the power an item would have?
you basically use rectifiers..like zener diode rectifier and full bridge rectifier..
What is the difference between p n junction and zener diode?
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
Can diode be used as rectifier?
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
What is the difference between an ideal zener diode and practical zener diode?
Zener diode is heavily doped pn junction diode.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
Is it pn junction diode used as voltage regulator?
zener diode
