Question

The maximum reverse bias voltage that can be applied to a reverse biased PN junction diode without damaging the junction is called _______.

• A. Breakdown Voltage
• B. Peak Inverse Voltage
• C. Reverse saturation voltage
• D. Bias voltage

Hint:

PIV is the "safe max reverse voltage" before diode breakdown. Always design circuits under this limit.

Answer 1

The Correct Option is B

Step 1: What is Peak Inverse Voltage (PIV)?
PIV is the maximum voltage a diode can withstand in the reverse-biased condition without entering breakdown.
Step 2: Difference from Breakdown Voltage
- Breakdown voltage is where the diode starts conducting in reverse (may be destructive for general-purpose diodes).
- PIV is the safe limit to be observed to prevent breakdown.
Step 3: Other options
- Reverse saturation voltage: no such defined term.
- Bias voltage: general term for applied voltage (forward/reverse).
Conclusion:
The correct and safest reverse limit = PIV → Option (2) is correct.
