प्रश्न
Differentiate between the threshold voltage and the breakdown voltage for a diode.
Advertisements
उत्तर
| Threshold voltage | Breakdown voltage | |
| (i) | The forward voltage at which the current through the p-n junction starts increasing rapidly is known as the threshold voltage. | Reverse voltage at which the p-n junction breakdown occurs is called the breakdown voltage. |
| (ii) | The magnitude of this voltage is lower than the breakdown voltage. | The magnitude of this voltage is higher than the threshold voltage. |
