Definition
Junction capacitance is the voltage-dependent capacitance associated with charge separation and depletion or stored charge at a semiconductor p-n junction.
Application
Used in device characterization and circuit design because reverse bias changes depletion width and capacitance, affecting switching, RF response, and C-V measurements.
