Study on the barrier capacitance characteristics of switching diode

Switching Diodes are used in high-frequency circuits, and their capacitance effect cannot be ignored. In this paper, based on the research of the barrier capacitance model of switching diode, the test method and test circuit of barrier capacitance was studied, and the influence of different voltages and working temperatures on barrier capacitance were analyzed, and some suggestions are put forward for device suppliers and users.
