We will discussed what is the application of zener diode as voltage regulator, now we will discuss the other two points briefly. The reverse bias characteristic curve of diode is shown in the fourth quadrant of the figure above. reverse bias voltage in this region is chosen, circuit per-formance parameters such as loss, distortion, and reli-ability must not be compromised. 2. It is conditionally safe region where most high-power (greater than 1 kW) p-i-n diode switches are designed to operate. This makes it applicable to making use of it in the regulation of voltages. Translations in context of "reverse bias" in English-French from Reverso Context: The other junction receives either a reverse bias or floating potential. We know that a Diode allows the current flow only in one direction and hence it acts as a one-way switch. Applications.

The photodiode is reverse biased for operating in the photoconductive mode. Q26. Potential Induced Degradation (PID) has recently been identified as one of the major field durability issues of PV modules. In effect, the reverse bias causes faster response times for the photodiode. The application of the V BIAS voltage (reverse bias) causes the photodiode’s junction capacitance to decrease. At very large reverse bias, beyond the peak inverse voltage or PIV, a process called reverse breakdown occurs that causes a large increase in current (i.e., a large number of electrons and holes are created at, and move away from the p–n junction) that usually damages the device permanently. note that the depletion region is shown much wider than in forward bias.
