Challenge Problems
Push your limits with challenges.
Question 1
A silicon diode has a knee voltage of 0.7V. If the reverse saturation current is 10nA, calculate the current at 1V forward bias.
💡 Hint: Use the thermal voltage at room temperature, about 25.86mV.
Question 2
Evaluate the effect of doubling the forward voltage across a diode that is initially at 0.7V. How does this affect the current flow, according to the Shockley equation?
💡 Hint: Think about how quickly exponential growth can escalate with small increases.
