There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
A zener diode, in the reverse bias condition, presents a higher voltage. The current, however, is a function of the supplying circuit.

What is the cause of reverse recovery time in a pn junction diode
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
the current which has negative value n passes through the diode is called as diode reverse current
When a diode is operated as reverse bias the current flow is almost completely blocked. A small amount of current is still able to travel in reverse through the diode and this is referred to as the reverse current saturation.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The reverse saturation current of a germanium (Ge) diode is the current that flows when the diode is in reverse bias and no significant forward current is present. It is caused by thermally generated minority charge carriers in the diode. This current is typically in the range of microamps to milliamps for Ge diodes.
diode current flows only when the diode is forward biased because in reverse bias the barrier potential increases. Diode can conduct in reverse bias if applied votage is high enough to overcome the reverse bias barrier potential but it can be destructive.
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
because semiconductor diodes are not perfect insulators when reverse biased. if you want a diode that is a perfect insulator when reverse biased, use a vacuum tube diode.
Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.
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.
A diode is an electronic component with the characteristic that its resistance is not constant, but depends on the magnitude of the current through it. An ideal diode has zero resistance to current in one direction, and infinite resistance to current in the reverse direction.
A zener diode, in the reverse bias condition, presents a higher voltage. The current, however, is a function of the supplying circuit.
