Volt-ampere characteristics and parameter of tunnel diode Volt-ampere characteristics of tunnel diode (see picture a) is a S pattern curve. The highest current point P in the curve is called the peak; the lowest current point V is called valley point. The main parameters of the tunnel diode are: (1) Peak point voltage Up is about dozens of millivolt; valley point voltage Uv is about hundreds of millivolt. (2) Peak point current Ipi is about several milliampere; valley point voltage Iv is about hundreds of microampere. (3) Proportion of peak point current and valley point current is about 5-6; the higher, the better. (4) Valley point capacitance Cv of from several microfarad to dozens of microfarad, and the lower, the better; 2BS4A made in China: Up=80 millivolt, Ip = 4 milliampere, valley point current proportion ≥5, Cv = 10～15 microfarad, Uv = 280 millivolt.
