Directions : In the following questions, A statement of Assertion (A)...
Assertion (A): When diode is used as a rectifier, its specified reverse breakdown voltage should not be exceeded.

Reason (R): When p-n junction diode crosses the reverse breakdown voltage, it gets destroyed.

The correct answer is option 'A', which means that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

Explanation:

Diode as a Rectifier:
A diode is a two-terminal electronic device that allows the flow of current in only one direction. It is commonly used as a rectifier in electronic circuits to convert alternating current (AC) to direct current (DC). In a rectifier circuit, the diode allows the flow of current in the forward direction (when the anode is at a higher potential than the cathode) and blocks the current in the reverse direction.

Reverse Breakdown Voltage:
Every diode has a specified reverse breakdown voltage, which is the maximum voltage that can be applied in the reverse direction before the diode starts conducting heavily in the reverse direction. Beyond this breakdown voltage, the diode enters the breakdown region and can be permanently damaged if the current is not limited.

Assertion Explanation:
The assertion states that when a diode is used as a rectifier, its specified reverse breakdown voltage should not be exceeded. This means that the reverse voltage across the diode should not be higher than the specified breakdown voltage. If the reverse voltage exceeds the breakdown voltage, it can cause excessive current flow through the diode, leading to its destruction.

Reason Explanation:
The reason states that when a p-n junction diode crosses the reverse breakdown voltage, it gets destroyed. This is because when the reverse voltage exceeds the breakdown voltage, the electric field across the p-n junction becomes very strong. This strong electric field can cause the diode to experience a phenomenon called avalanche breakdown or Zener breakdown, where a large number of charge carriers are generated, leading to a significant increase in current flow. This excessive current flow can cause the diode to overheat and ultimately get destroyed.

Conclusion:
In conclusion, the assertion and reason are both true, and the reason provides the correct explanation for the assertion. It is important to ensure that the reverse breakdown voltage of a diode is not exceeded to prevent damage to the diode when used as a rectifier.
