A P-N junction diode is a silicon. The P-N junction is the basic element for semiconductor diodes type. One of the terminals is doped with P- types material as well as the other with N - type of material.
The schematic symbol of P-N junction diode is made up P-type silicon and N-type silicon semiconductor materials.
Symbol of p-n junction diode :
