Diode Current Voltage Equation

Where i is the diode current i s is the reverse bias saturation current or scale current.

Diode current voltage equation. 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. The current equation depend on dark saturation current the charge of an electron externally applied a voltage and a constant. However at times the inverse relation may be more useful. Diode current equation expresses the relationship between the current flowing through the diode as a function of the voltage applied across it.

The ideal diode equation is very useful as a formula for current as a function of voltage. Diode current can be expressed by an equation called diode current equation. Zener diode zener voltage regulator calculator formulas and equations for zener diode zener voltage regulator calculator series current is vin vz. The diode law for silicon current changes with voltage and temperature.

We also provide a calculator for the diode current equation. 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. Large signal modelling shockley diode model. If the ideal diode equation is inverted and solved for voltage as a function of current we find.

Breaking news up tp 93 off launching official electrical technology store shop now. The associated current is a diffusion current and using a procedure similar to that for calculating the ideal diode current in a long diode one obtains the following hole current. The shockley diode equation or the diode law named after transistor co inventor william shockley of bell telephone laboratories gives the i v current voltage characteristic of an idealized diode in either forward or reverse bias applied voltage. Mathematically it is given as where i is the current flowing through the diode i0 is the dark saturation current q is the charge on the electron v.

8 22 2005 the junction diode forward bias equation doc 2 6 jim stiles the univ. 4 4 62 the electron current due to diffusion of electrons in the p type region is given by a similar expression. Of eecs now say a voltage v 1 across some junction diode results in a current i 1 likewise different voltage v 2 across this same diode a diode of course results in a different current i 2. An equation describes the exact current through a diode given the voltage dropped across the junction the temperature of the junction and several physical constants.

It is commonly known as the diode equation.
