Challenge Problems
Push your limits with challenges.
Question 1
If a silicon diode has a cut-in voltage of 0.65V and is placed in a circuit with a 1.5V power supply, calculate the expected current through the diode assuming a reverse saturation current of 20nA.
💡 Hint: Consider the impact of V_T at room temperature.
Question 2
Design a protective mechanism for a diode in a circuit where reverse voltages could exceed the rated reverse breakdown voltage. Explain your approach.
💡 Hint: How can you ensure the current remains within safe limits?
