Challenge Problems
Push your limits with advanced challenges
A PN junction diode has a reverse saturation current of 1 microamp at 25°C. Calculate the saturation current at 75°C, assuming an exponential increase with temperature with a coefficient of 0.3.
💡 Hint: Exponential functions multiply; think of how many times the current increases.
If a diode's threshold voltage decreases by 0.2V for every 10°C increase, calculate the new threshold voltage at 80°C if it started at 0.7V at 20°C.
💡 Hint: Apply the decrement to the original value based on the temperature change.
