Want this question answered?
zener diode is a revers bias diode which used for voltage regulation.
Forward bias is when the height of the depletion layer is reduced such that a greater number of majority charge carriers have sufficient energy to overcome the potential barrier while revers bias is when the height of the potential barrier is increased so that very few majority charge carriers have sufficient energy to surmount the potential barrier. All the above phenomena takes place when a potential barrier is applied across the pn junction.
Forward bias implies that your device is sensitive to bias direction and you have selected one of them. There is also an implication that it is probably a steady bias. So forward bias generally implies a dc bias in a selected direction called forward bias in the device you are looking at. Now the question is actually put the other way round. DC bias means a steady state bias. Whether or not it is forward or reverse bias depends on whether or not the device is sensitive to the direction of bias. If it is not sensitive to that, it isn't forward bias (or reverse bias either). If it is sensitive to bias direction, then it would be in a state of either forward bias or reverse bias, and you would need more information in order to say which one. So, finally, the phrase "dc biased" is NOT the same thing as "forward biased".
