Challenge Problems
Push your limits with challenges.
Question 1
A silicon diode has a reverse saturation current of 10 nA at room temperature. Calculate the expected current if the temperature increases significantly to 80 degrees Celsius.
💡 Hint: Consider the temperature effect on the diode's material properties.
Question 2
In a circuit with a Zener diode specified at 5.1V, calculate the series resistor needed if the input voltage is 12V and the Zener current should range between 20mA and 30mA.
💡 Hint: Calculate the voltage drop needed and then adjust for the expected Zener current.
