Electronic – How to calculate the voltage on the load in this circuit

diodestheveninvoltage

I've been try to solve this circuit for hours and have no idea on how to find the load voltage U_s.

enter image description here

I tried applying the Thevenin theorem to find the equivalent Thevenin voltage (using the voltage divider rule => E_Th = 6V) and also the Thevenin resistance (we take R_s and R in parallel and the result is going to be 5k (ohms)).

I don't know what to do next. Should I replace the diode with an open circuit because it is reverse biased? After that, is it okay if I say that the voltage on the cathode is V_C = E_0 = 3V, and compute the voltage on the anode using the voltage divider rule?

As was suggested in your previous question, redrawing the circuit may help:

OK. So that would result in the following circuit:

From that, what is your reasoning regarding \$I_D\$?
