I have a question. I know that when a pin diode is inversally polirized or in condition of zero bias, the model include a capacitor parallel to a resistor. Could someone explain to me why is better when this capacitor has a low value??
Hi, I think what you said is the dynamic behavior of diode. Under the situation, the diode is equated to a nonlinear capacitor in series a res. And the cap combines excess minority carrier charge and the space charge. Maybe small cap means fast transit time.
