WebApr 13, 2024 · The behavior can be most clearly seen on a graph of diode forward bias current vs. time. Driving voltage and diode current vs. time Because the diode is still conducting after the polarity switch, the current momentarily switches from positive to negative, and it remains negative for some time before decaying to zero. WebMay 24, 2024 · After that, current grows significantly more slowly than exponentially. The reason: real diodes aren't ideal. Besides the behavior modeled by the Shockley diode equation, they have non-ideal behavior like resistance. At low currents this resistance isn't very significant, and the voltage-current relationship is approximately exponential.
