Find the temperature at which a diode current is 2mA for a diode which has reverse saturation current of 10-9 A. The ideality factor is 1.4 and the applied voltage is 0.6V forward bias. Correct Answer 69.65°C

Equation for diode current I=I0×(e(V/ηVT)-1) where I0 = reverse saturation current η = ideality factor VT = thermal voltage V = applied voltage I0 = 10-9A, η = 1.4, V = 0.6V, I = 2mA We know thermal voltage VT = TK/11600. Therefore, TK = VTx11600 = 0x11600 = 342.65K = 69.65°C.
