Challenge Problems

Push your limits with challenges.

Question 1

In a specific circuit, a reverse-biased diode experiences a leakage current of 1 µA at -5 V. If the breakdown voltage is -50 V, calculate the expected current flow at breakdown, assuming an exponential increase.

💡 Hint: Consider the exponential relationship defined by the diode equation, and research typical values for current increase.

Question 2

You are designing a circuit that requires the protection of sensitive electronic components. How would you configure a reverse-biased diode within your protection circuit, and what considerations would you make?

💡 Hint: Think about real-world conditions that may cause voltage surges.
