Normally,the reverse current is so small that it can be neglected.If the external reverse-bias voltage is increased to a value( 50 V or larger) ,at this stage the reverse breakdown occours
What else can I help you with?
What happens when the diode is reversed in the circuit?
When a diode is reversed in a circuit, it becomes reverse-biased, blocking current flow. In this state, the diode prevents current from passing through, effectively acting like an open switch. If the reverse voltage exceeds the diode's breakdown voltage, it may enter a breakdown region, potentially damaging the diode unless it is designed to handle such conditions. Otherwise, under normal reverse bias, the diode will simply not conduct.
What is maximum voltage of a reverse bias diode explain and also defined?
The maximum voltage of a reverse-biased diode, known as the reverse breakdown voltage (or reverse voltage rating), is the maximum reverse voltage that can be applied before the diode begins to conduct in the reverse direction, potentially leading to breakdown. Beyond this voltage, the diode may experience a sudden increase in reverse current, which can damage the diode if not controlled. The reverse breakdown can be utilized in certain types of diodes, like Zener diodes, for voltage regulation. In general, reverse bias prevents current flow until this breakdown voltage is reached.

On what part of the curve is a reverse biased diode is normally oprated?
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.

What are specifications of pn junction diode?
This can vary significantly from diode to diode (especially the reverse recovery time and peak reverse breakdown voltage), so always consult the datasheet.

all most 50Volts when diode is in reverse bias.

What happens in the circuit when a1N4001 diode experiences its breakdown voltage of 50V?
If a diode breaks down in the reverse direction then, providing there is current-limiting resistance, nothing will happen to the diode. If there is no such current-limiting resistance the diode will be destroyed. Heat is the only enemy of a semiconductor of this type.
How are power diode classified?
by reverse breakdown voltage & forward current capacity
What is Meaning of diode rating?
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.
