Question

hey guys can anyone tell me what does it mean by current components in pn diode??

Answer 1

n-type semiconducter= negative charge carriers
p-type semiconducter= positive charge carriers
The p–n junction possesses some interesting properties which have useful applications in modern electronics. A p-doped semiconductor is relatively conductive. The same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and from there non-conductive, depending on the relative voltages of the two semiconductor regions.
By using this non-conductive layer, p–n junctions are commonly used as diodes: circuit elements that allow a flow of electricity in one direction but not in the other (opposite) direction. Therefore a P-N junction (diode).

Answer 2

in pn diode there are two types of currents,
one component is due to flow of electrons,another components is due to flow of holes
these two constitute the current components in a pn diode
