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. WebMar 12, 2024 · Main functions. The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version of a check valve. 2.
