Reverse Biased is when a large depletion region a the junction will offer a large resistance and permit only a small current. An  external voltage is applied across the p-n junction in the opposite polarity of the p-type and n-type materials. It satisfies the condition, (VD  < 0 V). The current that exists under reverse-bias conditions is called the reverse saturation current and is represented by Is.

  • The reverse voltage causes the depletion region to widen.
  • The electrons in the n-type material are attracted toward the positive terminal of the voltage source.
  • The holes in the p-type material are attracted toward the negative terminal of the voltage source.
