There are a number of PIN diode characteristics that set this diode apart from other forms of diode. Due to this large magnitude of an electric field, the electron-hole pair generation will augment up to a large extent and this, in turn, can process even a weak input signal. Whereas when the diode operates in forwarding bias conditions, there will be a thinner potential barrier.
