Step 1 of 2 3.027P The diffusion capacitance Cd and the forward current / is, (1) The diffusion capacitance Cd is directly proportional to forward current / Substitute 0.1 mA for mA for and 5 pF for Cd1 = 0.5 pF Step 2 of 2 From equation (1) the mean transit time of the junction is, = 0.5 pF Substitute 0.5 pF for Cd, 0.1 mA for I, 26 mV for VT which represents thermal voltage at room temperature in equation. = 130 ps Therefore, the mean transit time of the junction is 130
