IMPATT Diode

Introduction
When the pn junction diode is reverse-biased, then current does not flow.
However when the reverse voltage exceeds a certain value, the junction breaks down and current flows with only slight increase of voltage. This breakdown is caused by avalanche multiplication of electrons and holes in the space charge region of the junction.
The pn junct ....etc

PN-Junction Diode Characteristics

Forward Bias --- External battery makes the Anode more positive than the Cathode --- Current flows in the direction of the arrow in the symbol.
Reverse Bias --- External battery makes the Cathode more positive than the Anode --- A tiny current flows opposite to the arrow in the symbol.

Series-Connected Diodes

Use 2 diodes in series to withstand higher reverse breakdown voltage.
Both diodes conduct the same reverse saturation current, Is.
