Challenge Problems
Push your limits with challenges.
Question 1
Suppose a silicon diode has a reverse saturation current (IS) of 20 nA. Describe how to choose a Zener diode for voltage regulation in an application where the load varies significantly.
💡 Hint: Think about the expected load conditions and the Zener specifications.
Question 2
In a circuit, the total current flowing through a reverse-biased diode is measured at 50 nA when subjected to a reverse voltage of 5V. Discuss whether this current could remain constant if the applied reverse voltage is increased to 10V.
💡 Hint: Consider the limits of reverse bias behavior and when breakdown is likely.
