Challenge Problems
Push your limits with challenges.
Question 1
A silicon diode has a reverse saturation current of 10^-14 A. Calculate the current through the diode at 0.7V at room temperature. Assume q = 1.6 × 10^-19 C and k = 1.38 × 10^-23 J/K.
💡 Hint: Apply the diode equation while ensuring the correct unit conversions for temperature.
Question 2
In what scenarios would it be advantageous to use a Zener diode under reverse bias instead of a regular diode?
💡 Hint: Consider the implications of breakdown voltage on circuit design.
