Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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?
