The volt-ampere characteristics of a diode explained by the following equations: Where I = current flowing in the diode, I 0 = reverse saturation current V = voltage applied to the diode, V T = volt- equivalent of temperature = k T/q = T/ 11,600 = 26mV (@ room temp) =1 (for Ge) and 2 (for Si) Circuit Diagram: Fig. Thus, it is called Tunnel diode. For small forward voltages owing to high carrier concentrations in tunnel diode and due to tunneling effect the forward resistance will be very small.
