voltage drop

The decline in voltage in an electrical circuit due to the resistance in the conducting line. This is why longer electrical runs in a building require thicker gauge wire and why AC power is transmitted over high-voltage lines. Higher current requires thicker and more expensive wires, but higher voltage does not. The high-voltage lines are reduced by transformers near the end of the line. See voltage and ohm.

Aiding in the validation is the effect that conductivity of metals decreases with temperature, providing an indirect measurement of overall thermal performance; if the power shape is hotter than expected, it should experience a higher voltage drop. Measuring the voltage drop of an active design provides insight into the thermal characteristics of that design.
A negative (cathodic) voltage shift of at least 300 mV, as measured between the structure surface and a stable reference electrode, with consideration of voltage drops other than across the structure/electrolyte boundary
These voltage drops can be a source of problems when testing the pipeline to decide if it is receiving acceptable levels of cathodic protection current.
Key features of the Trench SBR SBRT15U50SP5 include ultra low forward voltage drop (VF) which helps to minimize power losses, excellent reverse leakage (IR) stability at higher temperatures, a thermally efficient package for cooler running applications, and has a less than 1.1mm package profile ideal for thin applications.
A Soft Start capability reduces current changes during sudden load activation which would normally force a voltage drop. The soft start setting limits the amount of input current at start-up or when the Von Voltage threshold is tripped.
The new NTST30100CTG, NTST20100CTG and NTSB20U100CTG family of devices use a trench topology that is presented as enabling exceptionally low forward voltage drop and reduced leakage current.
* The ability to prevent uncontrolled restarts by monitoring and tripping under conditions of extreme voltage drop or when the supply voltage is interrupted.
* Has contacts that offer low voltage drop and amperage-carrying capability.
