zener breakdown and avalanche breakdown.
A reverse-biased diode is typically operated in the reverse breakdown region of its current-voltage characteristic curve. In this region, the diode allows a small reverse current to flow, which is generally negligible until a certain breakdown voltage is reached. Beyond this breakdown voltage, the diode can conduct significant current, but in normal applications, it operates below this threshold to prevent damage. Thus, the diode primarily remains in the reverse bias region with minimal current flow.

A diode in a half-wave rectifier can be damaged if it is subjected to excessive reverse voltage, exceeding its maximum reverse voltage rating (peak inverse voltage, or PIV). This can lead to breakdown and failure of the diode. Additionally, if the diode conducts excessive forward current beyond its rated capacity, it can overheat and become damaged. Proper circuit design and component selection are essential to prevent these issues.
The breakdown voltage of a diode can be controlled by altering its doping concentration and the thickness of the depletion region. Increasing doping levels generally leads to a lower breakdown voltage, while a wider depletion region can increase it. Additionally, the diode's material properties and structural design, such as using different semiconductor materials or introducing guard rings, can also influence the breakdown voltage. By carefully engineering these factors, manufacturers can create diodes with specific breakdown voltage characteristics to suit various applications.
The breakdown voltage of a diode is the minimum voltage at which it conducts in both directions. If you have a 100-volt rectifier diode (1N4002) and you wire it into a 110v circuit, it will flow current in both directions and you'll get no rectification.
The difference is , the break down in a zener is desirable, well designed, expected, healthy and designed for a particular value. After breakdown, it can and is expected to maintain that condition for a long time. zener is optimized to work in this region.They are designed to have very low breakdown voltages. In contrast, the break down in a rectifier diode is undesirable, not well designed, not respected. This diode is optimized to work in the rectifier region and optimized for that. Breakdown region is avoided in normal operation. The breakdown voltage is normally very high, above 100 volts.
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.

yes, diode can be used as rectifier diode to convert ac to dc
False, a zener diode is normally operated reverse biased in breakdown.

yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
tunnel diodethe doping level of the tunnel diode is high when compared with the rectifier diodeit exhibits negative resistancerectifier diodethe doping level of rectifier diode is low when compared with the tunnel diode
A diode is used primarily as a Rectifier
The zener diode protects the meter by stabilizing the voltage when it goes in to the breakdown region.
