  Any variation of the charge within a p-n diode with an applied voltage variation yields a capacitance wich must be added to the circuit model of a p-n diode. The capacitance associated with the charge variation in the depletion layer is called the junction capacitance, while the capacitance associated with the excess carriers in the quasi-neutral region is called the diffusion capacitance.
  
  Hey is your question diffusion capacitance? Coz depletion region is there but no depletion capacitance I guess...

  You can say that.
