  2. Shockley diode equation - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode_equation

    The Shockley equation is a constant current (steady state) relationship, and thus doesn't account for the diode's transient response, which includes the influence of its internal junction and diffusion capacitance and reverse recovery time.

    J 0, reverse saturation current density (ampere/cm 2) r S, specific series resistance (Ω·cm 2) r SH, specific shunt resistance (Ω·cm 2). This formulation has several advantages. One is that since cell characteristics are referenced to a common cross-sectional area they may be compared for cells of different physical dimensions.

  4. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).

  5. Diode - Wikipedia

    en.wikipedia.org/wiki/Diode

    From the Shockley ideal diode equation given above, it might appear that the voltage has a positive temperature coefficient (at a constant current), but usually the variation of the reverse saturation current term is more significant than the variation in the thermal voltage term.

  6. Shockley diode - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode

    The Shockley diode (named after physicist William Shockley) is a four-layer semiconductor diode, which was one of the first semiconductor devices invented. It is a PNPN diode with alternating layers of P-type and N-type material.
