1. The problem statement, all variables and given/known data A Si diode is operated at the room temperature (27 °C). For a forward current of 1 mA, the voltage VD is found to be 0.9 V. If the VD is 1 V, the forward current = _____ mA. Given that nVT = 26 mV The answer is 46.81 2. Relevant equations Shockley diode equation? 3. The attempt at a solution I tried to use the shockley diode equation, Id=Is exp(Vd/nVt) I subbed in values 0.9V and 1mA into eqn to get Is and then using newfound Is to sub into shockley diode eqn again with Vd 1V now. However, I didn't get the answer 46.81mA. Is there an assumption that I have made wrong? Any help in figuring my mistake out is greatly appreciated. Thank you so much!!
