The reverse saturation current for a Germanium diode at a temperature of 293 K is found to be 2 μA. What is the reverse saturation current Is at a temperature of 313 K?

The reverse saturation current for a Germanium diode at a temperature of 293 K is found to be 2 μA. What is the reverse saturation current Is at a temperature of 313 K? Correct Answer 8 μA

The reverse saturation current for a silicon diode doubles its value for every 10 K rise in temperature. Hence Is at 313 K=2 x 2 x 2 = 8 uA.
