Help. This is about Diodes

5. A diode has a reverse saturation current of 6 x 1015 A and an ideality factor of 1. If its DC
operating voltage is 0.68 V and it is operating at 300°K, what is its small signal resistance in
ohms? Express your answer to two decimal places.
8. A diode with forward voltage of 0.74 volts and forward resistance of 5 Q is to be connected
between A and B with the anode connected to A. What value of vIN in volts will the diode start
to conduct?
A

9. The purpose of the Zener diode is to maintain the voltage across the load at 11 V. The load
draws anywhere from 0 to 400 mA of current. If R = 9 Q, what is the minimum value of Vs that
will guarantee the circuit will work properly.
