Description [Unit] Parameter Name Data Type
Value of the Diffusion Capacitance VAL real
>>Basics>Tools>Characteristics
The junction capacitance represents the dependence of the resulting junction capacitance
from the applied voltage due to the majority carrier distribution. The junction and the diffusion
capacitance were developed for modeling the dynamic switching behavior of a diode or another
semiconductor component.
