What is true about the breakdown voltage in a Zener diode ?
Correct answer: D. It is approximately constant
- A. It decreases when load current increases
- B. It destroys the diode
- C. It equals current times the resistance
- D. It is approximately constant
Explanation
Once breakdown occurs, the Zener voltage remains approximately constant over its specified operating-current range. Increasing load current changes the current and may cause a small voltage variation, but does not normally destroy the diode if power limits are respected.
