The diode is a specialized electronic component with two electrodes called the anode
and cathode. Most diodes are made with semiconductor materials such as silicon,
germanium, or selenium. Some diodes are made of metal electrodes in an evacuation
chamber or filled with pure elemental gas under low pressure. Diodes can be used
as rectifiers, signal selectors, voltage regulators, switches, signal modulators, signal
mixers, signal extracts.
2- Introduction
Construction of diode
-Diodes made of either of two semiconductor materials silicon and germanium.
Power diodes are usually constructed using silicon.
- Silicon diodes can operate at higher current and at higher junction temperatures
and they have greater reverse resistance.
-a semiconductor device with two terminals, typically allowing the flow of current
in one direction only.
-The structure of a semiconductor diode and its symbol are shown figure below. The
diode has two terminals an anode A terminal (P junction) and cathode K terminal (N
junction).

, -When the anode voltage is more positive than the cathode, the diode is said to be
forward-biased, and it conducts current readily with a relatively low voltage drop.
- The arrow on the diode symbol shows the direction of conventional current flow
when the diode conducts.
