Diode Cap<strong>ac</strong>itance<br />
In reverse bias, <strong>th</strong>e depletion layer is very large. The diode’s strong positive and<br />
negative polarities create cap<strong>ac</strong>itance, C T . The amount of cap<strong>ac</strong>itance depends<br />
on <strong>th</strong>e reverse voltage applied.<br />
In forward bias storage cap<strong>ac</strong>itance or diffusion cap<strong>ac</strong>itance (C D ) exists as <strong>th</strong>e<br />
diode voltage increases.<br />
