位移电流的机理只对反向偏压或要维持空间电荷层所需要的非常弱的正向偏压条件下的电容器才有用。

The displacement current mechanism is operative only for capacitors under reverse bias or very weak forward bias conditions which maintain a space-charge layer .

当正向偏压足够高时，扩散电容很容易超过空间电荷压电容。

With sufficient forward bias, the diffusion capacitance can easily exceed the space charge region capacitance.
