Which of the following represents a complete, standard set of Zener diode operating ratings?
Which of the following represents a complete, standard set of Zener diode operating ratings?
Multiple Choice Options
- A
10V voltage, 25-40V current range, Zener current = 5mA
- B
Voltage = 5V, Current = 10mA
- C
Voltage = 20V, Current range 15- 30mA
- D✓ Correct Option
None of the above
Detailed Technical Solution & Explanation
A complete specification for a Zener diode voltage regulator requires a nominal Zener breakdown voltage (), maximum power rating (), and minimum knee current (). The given incomplete choices do not specify valid design operating constraints.
Option Analysis:
•
Option A (10V voltage, 25-40V current range, Ze...): Incorrect. Mixing voltage units with current ranges indicates malformed parameters.
•
Option B (Voltage = 5V, Current = 10mA): Incorrect. Lacks complete operating window.
•
Option C (Voltage = 20V, Current range 15- 30mA): Incorrect. Incomplete specification.
•
Option D (None of the above): Correct. None of the listed options provide a complete, physically valid Zener diode rating set.
