What is the purpose of N layer in power diode?Its function is to absorb the depletion layer of the reverse biased p n- junction. As it is lightly doped, it will add significant ohmic resistance to the diode when it is forward biased. For higher breakdown voltages, the drift region is wide. The n- drift region is absent in low power signal diodes - Study24x7
