Since the standard pn junction diode is not constructed like a zener diode (zener diodes actually have pn-pn arrangements on its die internally), it will short out in its typical circuit design due to the lack of current limiting.

WebbStudy material notes on 1- V characteristics in forward bias and reverse bias, we can get at a fact – a PN junction diode conducts current only in one direction – i.e. during forward bias. During forward bias, the diode conducts current with an increase in voltage. During reverse bias, the diode does not conduct with an increase in voltage.

WebbDiffusion capacitance occurs in a forward biased p-n junction diode. Diffusion capacitance is also sometimes referred as storage capacitance. It is denoted as CD. In a forward biased diode, diffusion capacitance is much larger than the transition capacitance. Hence, diffusion capacitance is considered in forward biased diode.
