The ground may be the … WebMeasuring leakage current and insulation resistance involves measuring very small values. To get more accurate readings, connect the DUT to the Model 2450 rear panel with low-noise triaxial cables. Connect the DUT between the FORCE HI and FORCE LO terminals of the Model 2450. Figure 2 shows schematic diagrams. WebIn semiconductor devices, leakage is a quantum phenomenon where mobile charge carriers (electrons or holes) tunnel through an insulating region. Leakage increases exponentially as the thickness of the insulating region decreases. Tunneling leakage can also occur across semiconductor junctions between heavily doped P-type and N-type semiconductors. signing date of this agreement
