FIELD: electricity.;SUBSTANCE: invention uses the known method of series resistance measurement for diode base wherein direct current of different values is passed and voltage drop is measured at these values of direct current. The unknown value of diode base series resistance is defined by the known formulae. In order to achieve technical result direct current is set as three sequences of short rectangular pulses of high duty cycle and amplitude I1, kI1, 2kI1 and peak value of voltage U1, U2, U3 drop is measured at the diode when these current pulses are passed. Series resistance of the base is defined as per the formula where ΔU32=U3-U2; ΔU21=U2-U1; ν=ln 2/b; b=ln k.;EFFECT: improved accuracy of series resistance measurement at the diode base by exclusion of backheating of the diode p-n-transition by current passing in the process of measurement.;3 dwg
