Step 1 of 2 3.020P The saturation current is, I, = + Substitute C for q, which represents charge of an electron 100 µm² for A, which represents cross sectional area 5 for which represents distance travelled by holes during their life time 10 µm for which represents distance travelled by electrons during their life time 10 cm²/s for Dp, which represents diffusion constant for holes 18 cm²/s for which represents diffusion constant for electrons for NA, which represents acceptor concentration for ND, which represents donor concentration for n, which represents intrinsic carrier concentration = = = Therefore, the saturation current value is Step 2 of 2 The forward current / is, Substitute A for Is which represents saturation current 750 mV for V, which represents applied voltage 26 mV for VT, which represents thermal voltage at room temperature Therefore, the forward current value is
